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

Definition: When someone ignores your messages for days, then posts something impressive on social media to remind you they’re "still winning."
Example:
"He didn’t reply for a week but just posted a gym selfie with a Lambo in the back—classic ghost flexing."
