A chin beard, usually short and well-groomed, that is purposely shaved into the shape of a triangle pointing towards one's lower lip, with no other hair on the person's face (mustache, sideburns, etc.) The name comes from the fact that a person who has it is usually a douchebag.
Person 1: Wow, that fucker just flipped me off! Is 50 in a 40 zone not fast enough for him?
Person 2: Doesn't surprise me, he's got the douchebag triangle.
An extremely lame dance performed at clubs or parties in which the dancer slowly bounces up and down in time with the music while twisting his upper body slightly from side to side. The dancer's feet remain on the ground, and arms stay motionless at the dancer's sides.
This dance is performed primarily by douchebags, mainly because it is the only dance that they are able to perform besides grinding.
-"Let's go. This club is full of assholes."
-"How do you know?"
-"Everyone's doing the douchebag shuffle."
