Size up

To get a feel of someone's strength by observing them or a call out to get someone to fight you

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 1: Bro, I fucked your mom

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
