You Deadass have a dick that can bend and go like a motherfucking helicopter in that wet ass pussy.
*during sex*
Oh yes daddy please use your big dick flex maneuver on me oh yea~
* Fucking DEMOLISHES THAT FUCKING BITCH LEAVING HER MOTIONLESS IN ORGASM*
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!"
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
