Size up

The phrase "size up", usually used in arguments, essentially means to "stand up and fight"

In other words...

This pretty simple term which was then redefined by tiktok idiots into: When a man looks if his dick will fit by checking out a girl's thighs.

Bro 2: Size up, bitch.

Bro 1: Bet

What tiktok idiots think it is:

Girl: OMG you're so gross, why are you sizing me up?

Boy: Umm... I wasn't. I don't want to fight
