the word flex usually means to bend a joint, but in this case, to flex something means to steal something that is not yours, so its a verb.

Delayed Flexing

Delayed Flexing in the simplest terms, is during the time that school comes back in, waiting to flex until after everyone else come back from the summer. Every body will wanna flex on them thotties when they come back from summer right? We’ll, wait till them broke ass boys are done and then come back one week looking fresh AF. Then you’ll stand out to them hot hunnies ya know?

Broke ass boy: Damn how is Tommy pulling all these hoes? I came back looking nice as hell and got no booty.
Other broke ass boy: Shit we all flexed at once and he waited to hella flex and now they don’t see us. He really got us with the Delayed Flexing
Brokeass boy: Fuck I guess
