The Joey is a variation of the batwing where the skin of the scrotum is stretched out then raised above, just exposing the bellend of the penis. After they see your balls/penis it is critical to insult them for being such a faggot while you are kicking them in the ass for looking at it.
Moe: JOEEEY!! (while exposing the Joey)
Alex: god damnit
Moe: Thats 5 kicks you faggot! I can't believe how gay you are.
