The prizewinning standout member in any given group of douchebags. Shortened from "Group Douche" (and yes, every group has one).
See the one on the right who's talking over everyone else and making a big show over his iPhone? Ok, the guy next to him with the popped collar, orange tan and inability to stop "adjusting himself" is obviously the grouche.
