butt mitzvah

it occurs on a jewish boy's mar bitzvah.
he and his friends, after the bar mitzvah (and the wine...) realize all their gay feelings for eachother and have a huge, gay, drunken, jew, underage orgy.

Larry, why are you walking all funny? come over here and give grandma goldstein and rabbi a hug!

MOOOOOOOM! My ass is sore, after my bar mitzvah, me, chaim, shlomo, and uncle ernie had a butt mitzvah!
