bar mitzvah slut
1) A young girl of the age of twelve or thirteen two gives oral sex to young gentlemen in the stalls during a bar mitzvah party. Typically, these girls are JAP's who think they need to give head to prove themselves. 

2) A old dirty girl who likes to pleasure herself with toys in the stalls of a bathroom during a bar mitzvah party, usually followed by exploding diarrhea. Typically, she can be notified by 6 tattoos on her face, and four on her lower thigh. They are too ugly to live and prey on young boys about the age of 6.

Bergs: I just heard a lady pleasure herself in the bathroom.
