from when Howard Dean flipped out.."BEEYAW!!" can mean a variety of things.."take that!" but it's primary purpose is to shout when you hit someone, making it seem more violent than it really is.
I walk up to my buddy and punch him in his shoulder while shouting "Beeyaw!"...or any other form of friendly violence..
