flexing her cunt 

When one is publicly displaying how much of a cunt they are.

At a Michael's Craft Store

Woman checking out at register - "I wanna speak to the manager. I've been waiting on this line for 1 minute! I need to pay for my 30 bags of chocolate like a fat fuck! This place is the worst!"

Correct response to this horrible person - "Wow! Look at that woman over there flexing her cunt!"

Flexing your facebook muscles 

When somebody on facebook will start fights and act tougher than they really are just because they have the protection of the internet with them. They do this to make themselves feel better just like flexing their muscles.

Tough guy: Hey you bitch whore, these scenic pictures you took really fucking suck.
You: Why are you trying to start something? What are you trying to prove? Quit flexing your facebook muscles.
Tough guy: Hey I'm sorryz for being so mean. I owe you for life. I'm going to go wash my face in shame now.

Flexing Chimps 

What is a flexing chimp may you ask? A Flexing Chimp is a proud Chimp that loves to play hypixel skyblock and fuck dudes. Also, a flexing chimp is known as a outcast in real life. But the people that see them as outcasts are fucking morons that should be sold to slavery, or left to die of hunger. Also, a chimp that is flexing penis is so big, that it will break any destroy any pair of pants.

flexing his dick 

When a man is attempting to strut his shit unfathomably hard; one's attempt at exerting the air of being macho to the parties around him in any shape or form. As when you see a guy driving a raised truck with expensive shocks and off-road tread tires, but still only drives in the suburbs.

"Dude, why was that cop who pulled us over such a fucker!?"
"Cuz there was a female cope partnered with him yo. Too busy flexing his dick in front of her."

(Man revs Harley obnoxiously loud as he drives by) "DICK FLEX!"
