A Jewish celebration where a girl of 12 or 13 pretends to read in Hebrew even though she really only memorized the transliteration then dances the electric slide in front of family she doesn't even know. She wears an ugly poofy dress and will regret that day for many years to come.
Jew "are you coming to my Bat Mitzvah?"
unsuspecting Goy " Yeah! it'll be awesome!"
