(v) when one or more men go out to a club, a bar, or the local McDonalds strictly to hit on and/or hook up with fat chicks or plumpers. Plumping usually requires a wingman in order to deal with the skinny, attractive girls, but not always.
"Hey dude, me and Joe are gonna go plumping tonight, wanna come?"
"Sure, I love to go plumping, do I have to be the wingman again? I hope not."
