In the eyes of older folk, there might not be much difference between millennials and Gen Z.
But a scroll through TikTok shows that the newest generation are sniggering at young adults across the country.
In particular, they seem to be hating on our hair.
This came to our attention after one user, who goes by the name of @missladygleep, shared a viral video claiming that side partings - a hairstyle adored by many millennials - were no longer on trend.
"Prove me wrong, but I don't think there is a single person who looks better with a side part than they do a middle part," the Gen Z TikTokker said.
Gen Z refers to anybody born after 1997. So basically, 23 year olds and under.
Lady Gleep isn't alone in her opinions, either. The hashtag #middlepart has racked up over 151.82m views on the app, and counting, with tonnes of younger users laughing at the older generation, while us millenialls also chime in, to question when they suddenly got old.
Pointing at her middle parting, one millennial asked: "Is this why I'm not getting carded (ID'd for alcohol) any more?"
While another joked: "Me, a lifelong side-parter, forcing a middle part so Gen Z doesn't know I'm old."
It isn't just hair that TikTokkers have an opinion on, they also have a lot to say about skinny jeans, too.
In fact, TikTok user @momohkd recently shared a video telling the older generation to burn their skinny jeans, or throw them away for good.
Emojis are also being discussed online, and the verdict is that the laughing emoji is 'out'.
"What's wrong with the laughing emoji[?]," one user questioned in a comment on the app, while another responded that using it was "so off."
"As a 15 year old I say you should use that emoji bc [because] we sure aren't going to," another chipped in.
While 21-year-old Gen Z Walid Mohammed, told CNN: "I stopped using it a while ago because I saw older people using it, like my mom, my older siblings and just older people in general".
It turns out the skull emoji is typically used instead now - to mean 'dead' (you know, laughing so much you're dead).
Of course, some people aren't choosing to listen to the Gen Zers when it comes to deciding what's cool and what's not.
"I'm sorry," wrote TikTokker @taylorrainmusic, "but the generation that ate Tide Pods does not get a say in where the part in my hair goes or what pants I wear. Thanks."
