Wow! Michaela must have been a really bad student in physics class for her teacher to react like this. Either that or her teacher was just plain evil.

This one really isn’t so bad. It can be frustrating when people think you look a lot older than you really are, but looking younger is usually a positive thing! It’s not great when you want to buy alcohol though.

This dad is too cool for school with such a frosty insult. We can’t help admiring his sense of humor, but we definitely wouldn’t want to get on his bad side.

It’s always painful when someone points out something you have a complex about. There’s nothing wrong with pale skin, but maybe this person needs to get out in the sun a little more.

Plenty of people have been in Mike’s position. It’s never fun. It’s never nice. We hope you got invited to plenty of other parties, later on, Mike!

An insult always hurts more when it comes from someone close. We expect our parents to have our backs, big us up, and make us feel great about ourselves. Sometimes, however, they choose not to do any of those things.

Many people are already pretty self-conscious about how they look, and it never helps to hear something like this. The DMV lady was probably trying to be nice, but once again, we see how good intentions can sometimes result in the coldest comments.

Cathy deserves credit for plucking up the courage to say what she said, but she probably regretted it immediately after hearing this cold, cruel reply from a mean co-worker.

Imagine hearing this one from your very own sister. This poor girl needs some hot cocoa, a warm bath, and a hug after such a cold insult.

Here’s another dad joke, taken a little too far! Who needs enemies when your dad busts out savage burns like this on a regular basis?

We’ve seen some dastardly dad burns throughout this list, but this one might be the harshest of all! This dad deserves a ‘Worst Dad Of The Year’ mug for Christmas.

It sounds like the kids need to be on their best behavior in Miss Porting’s class! Every one of us has had a scary teacher like her at some points or another.

It’s amazing how just a few words can ruin a day or even break down someone’s dreams! This simple comment reminds us all to be a little more careful with the words we choose.

Many kids grow up feeling like their brother or sister is the ‘favorite’ of the family. Poor Steve had his suspicions confirmed when his mom called his brother her “only good son”.

Kids can come up with some of the coldest insults of all. They don’t always even intend to be cruel, but they say what they think, regardless of how it sounds. Here’s a perfect example of that, for one unfortunate mama.

Giving compliments definitely doesn’t seem to be this mom’s strong suit. Still, being pretty isn’t exactly a bad thing.

This is why you should never read your kids’ journals. You never know what kind of secrets you might uncover. Sounds like it’s time to improve the pork chops recipe.

This mom was trying to teach her son a valuable lesson about the importance of being true to yourself and being happy in the skin you’re in. Unfortunately, the kid didn’t quite get the message.

We’ve seen a few examples of moms and dads being mean to their own children, and now we have an example of parents insulting other parents! At least she said something nice about the kids, but the implications for the mom and dad aren’t too pleasant.

Lots of kids make jokes about their parents being really old, but this one really takes the cake! It’s always funny to see how kids have absolutely no filters on the things they say.

Being a parent isn’t always as exciting and lovely as it seems to be. It comes with a whole lot of challenges, so we can’t blame this mom for taking the easy way out with some frozen food. However, it sounds like her daughter wasn’t too impressed.

We have to wonder if Latife’s best friend really meant this as a compliment or a criticism! It definitely doesn’t sound like something we’d like to hear.

One of the golden rules of parenting is that you always, always, always act like your kids’ drawings and paintings are works of art! You put them on the fridge and hang them up around the house to help them feel good about themselves, even if they aren’t all that great in reality. Apparently, Nicolle’s mom didn’t get the memo.

We put so much trust in our medical professionals. We have to tell them all kinds of embarrassing things and we hope they’ll treat us with care and compassion. Unfortunately, that isn’t always the case, as we can see here!

Whether he intended it or not, this little boy delivered one of the harshest burns on our list. He’s clearly destined for a future in the world of food criticism.

We have to wonder if Amy and this other girl are still friends after such a harsh comment. Nobody wants to hear something like that from someone they consider to be a buddy.

We’re noticing a bit of a theme throughout this list. The harshest comments of all constantly seem to come from children! And the younger ones tend to be meanest of all, even though they probably don’t mean to be.

This is one of the funniest entries on our list, and it’s all down to the way the mom responds. She was the one who gave the girl a bad haircut in the first place. Instead of apologizing, she joined in with the bullying!

Christmas would never be the same again for Kaarin after hearing this super harsh comment from her very own mother! Talk about a Scrooge!

Jimmy Fallon created this whole hashtag, but he also joined in on the fun, sharing one of the frostiest insults he ever received. Keep on truckin’, Jimmy. All that hard work will pay off in the end!

Many kids look at their parents to imagine how they might look when they grow up. So when any boy sees their dad losing his hair, he tends to worry. This guy’s son is savoring his locks while he can.

Chasdity’s mom was just trying to say something kind, but it came out all wrong! At least her handwriting is still ‘pretty good’ by 6-year-old standards. Most grown-ups have awful handwriting nowadays.

This is what being a brother or sister is all about. Playing mean tricks on your sibling and doing absolutely terrible things to them, but loving each other through it all.

We’ve seen DMV workers appear on this list a couple of times already now. It seems like they’re some of the frostiest people around. No wonder nobody likes going to the DMV.

No kid ever wants to hear that they were an ‘accident’. Unfortunately, Corinne had to hear it direct from her own dad in one of the iciest insults in our list.

There are two ways of looking at this particular comment. On the one hand, we can say that the girl thinks her mom’s regular cooking is pretty bad. On the other hand, maybe she’s just an easy-to-please kid who loves chicken nuggets!

We all know that one parent is usually a better cook than the other, but we tend to keep our opinions to ourselves, at least when we’re older. These kids, however, weren’t shy about letting their mom know exactly how they feel about her cooking.

Even big corporations are joining in with the frostiness! Many people worry about their friend and follower counts on social media networks like Facebook and Instagram, and cheeky messages like this one from FB definitely don’t help the situation.

Jen really needs to be careful around her little sister! She sounds like a supervillain, pulling off a terrible scheme like this. It had to hurt for Jen to make all that effort and feel like she wasn’t getting anywhere at all.

As we’ve seen throughout this list, some of the harshest insults aren’t actually intentional! Sometimes, people are trying to be nice or pay someone a compliment, like Geena’s dance teacher here, but it sounds a lot meaner than it was supposed to.

This one had to hurt. Poor Sharon had been working in a retail job for a whole month but her co-worker still didn’t recognise or remember her!

Another prime example of cheeky siblings being super mean to one another! Wendy’s sister must have been pretty proud of this one.

Stephen had to have felt pretty bad after hearing this comment from a waitress. Still, at least he got some cheap food out of it!

Ouch! That’s gotta hurt. Maybe the person who said this comment didn’t actually mean for it to come out so cold, but it couldn’t have been too nice for poor Amanda to hear.

Gee, thanks, mom! We just had an example of someone having to hear that they were in an accident. Now, this mom has gone one step further, casually implying that she never really wanted a fourth kid in the first place.

This really isn’t what you want to hear from your teacher! Nobody wants to feel like the dumbest one in the class. Aren’t teachers supposed to inspire their students?
