Horned Bird
A bastardization of giving someone the finger and throwing the Devil Horns gesture made popular by the Heavy Metal community. This is either done because someone is too tired to care, because they are a poser, or because they were torn between telling someone to rock on and fuck off.
My buddy had his picture taken with Isahn at Prog Power. He obviously didn't want it taken, can't you see the Horned Bird he's giving the camera?
