wearing bright or colorful clothes, jewelry, or other accessories when trying to pick up some booty
dude 1: "man, i'm good at talking to chicks but sometimes it's hard just to get their attention."
dude 2: "try using a little peacockery."
1. Showing off excessively to make oneself look sophisticated, refined or desirable in some way.
That peacockery won't impress me, I'm looking for someone with real skills.
