Another word for douche bag, jerk, or ass hole. Instead of saying douche bag, you can say Juice Box to avoid getting in trouble with teachers or parents. Also works around little children; they have no idea what you are saying, so it stops them from repeating the word or asking questions...
BOB: Dude! Ted just made me do the rest of his shift!
BILL: What a Juice Box!
