'Cousin face' is the weirdest new social media trend everyone can relate to

From daily activities to relationship tests, TikTok loves to put a label on just about anything.

Take 'bed rotting' for example, a term used to describe simply staying in bed all day.

Or the 'orange peel theory,' the name for a relationship test that sees if your other half is willing to small things to help you out.

The latest trend to sweep the social media site is dubbed 'cousin face' and it's actually pretty relatable.

It all started when TikToker @eviefsb was introduced to someone new by a mutual friend.

She recognised her new acquaintance immediately but couldn't put her finger on why, so she asked whether they'd met before.

"She goes, 'Oh that’s just because I have cousin face,'" Evie says.

"I was like, 'What the f*** is cousin face?' And she goes, 'Everyone’s always like, 'you look like my cousin. You look like my cousin’s cousin.' I look like everyone’s cousin.'"

At that point, Evie points out that they did look 'similar' and that she too has cousin face.

The video has since gone viral, being viewed more than two million times, and thousands took to the comments to share their thoughts.

One person wrote: "You don't look like any of my cousins but if I was casting for a part that was just 'cousin' I was def call you in."

Another said: "You do kinda have cousin face."

And a third commented: "We are all cousins to a point."

The topic was later brought up on American radio programme, The Kidd Kraddick Morning Show.

One of the show’s personalities, Ana Szabo, explained the viral trend.

"It’s basically when you see someone and you’re like, 'I think I know them from something,' or like 'Maybe they’re a friend of a friend or we’ve met before,' but you’re not entirely sure.

"Somebody who looks…I don’t want to say bland, but like someone you’ve met before."

Speaking of going viral, the Hawk Tuah girl is making the most of her time in the spotlight, recently appearing as a guest star for a music icon.

Hailey Welch was catapulted to her five minutes of fame after she and a friend were interviewed on the street.

When asked, 'What’s one move in bed that makes a man go crazy every time?' she responded with the now iconic line: "You gotta give ’em that 'hawk tuah' and spit on that thing!"

She recently took to the stage with country singer Zach Bryan at a concert in Nashville.

Wearing a tan cowboy hat and white top, she jumped up on stage for his hit 'Revival' even taking the mic all her herself at one point.

And people are loving the unexpected collaboration, calling Bryan a 'legend.'
