1. The preliminary acts to beating someone's ass.
A flex occurs when a trick ass mark is being a silly bitch and he/she recieves the big show.
That mark ass trick just scuffed my shoes, I'm about to flex his bitch ass.
A primary subject of recieving flexxing would be Alain P. because that dumb beaner is always running his mouf.
