Sex-flex

A personality trait formed of boasting about sex/sexual activities usually done by a person who has recently begun having sex after a long dry spell. The change in subject to sex in the group is also likely to have been brought up by the same person, making tenuous links to otherwise non-sexual discourse.
(Flexing about sex)

Person 1: Jake wouldn’t stop going on about how many times he has sex last week
Person 2: yeah he’s got sex-flex at the moment

coordinated flex

Flexing done prepared, not just out of the blue. Originated from Lil Tay's flexing, and the opposite of uncoordinated flex in which people flex at anytime anywhere.

Lil Tay's been doing a coordinated flex, it's revealed she's not rich.

Flex or fold

The act of “putting your money where your mouth is” by rising to the occasion or backing down. Much like “nut up or shut up”, it is a challenge to someone who has said that they would do something to show strength—usually an aggressive or bold course of action. It is frequently an ultimatum to call someone’s bluff after they’ve been running off at the mouth about what they could or would do in any given situation. The term is used to shut down foolish declarations made by wanna-be types who have something to prove to themselves and others, but they often lack the ability to follow through.

Girl #1: “If Karly tries to step to me, she can catch these hands!”

Girl #2: “I think Karly might have heard what you said…she’s coming over here.”

Girl #1: “I don’t care if she heard!”

Karly: “Oh, yeah?!? Flex or fold!”

Girl #1: “JK, Karly…you know you’re my girl.”

(After mean-mugging Girl #1)

Karly: “That’s what I thought.”
