A coming-of-age ceremony in the Jewish religion. When a boy turns thirteen, he is considered a man and reads a torah portion in front of friends, family and his shul. Bat Mitzvahs, the counterpart for 13-year-old girls, started in the early 20th century. Bar and Bat Mitzvahs are really supposed to be holy ceremonies that mark a child's emergence into the adult world of Judiasm, but in some parts of the US the parties are all that matters. Yes, it's very important for each young teen to out-do each other. Whether it's having expensive DJ's or balloon arches, invitees of Bar/Bat Mitvahs know they will have a great time and end up with a giveaway, like a t-shirt or pj pants with a cheesy saying. (Read: "I danced my pants off at Lauren's Bat Mitzvah!") For young teens that are or know Jewish teens, Bar and Bat Mitzvahs are the social highlights of the 7th and 8th grades.

Slang: On AIM "BM"
Mr. Cohen: My daughter is getting Bat Mitzvahed in January.
Mrs. Berg: I am so proud of her! Mazel Tov!

Rebecca: Like, Omigod, so I am getting a chocolate fondue fountain during my Bat Mitzvah party!
Elana: Um, Katie already had one of those.
Rebecca: No! My party must be better than hers! Now I'll get hula dancers. HA!

Ben: I scored 7,653 bucks from my Bar Mitzvah.
Andrew: Well I scored 8,127 bucks. Plus a new laptop. HA!

Coming of age celebration for Jewish children. Not a reason to generalize about an entire religion, or make yourself look like an ass.

A game played by tweens and teens. During a Bar Mitzvah, a Jewish coming of age celebration, the kids grab as many bottles/glasses of alcohol left on the table and drink the remaining liquid while the parents are too busy to notice. Whoever can drink the most before getting caught, passing out, or party's end is declared the winner.

The game has spread in popularity to many pre-college locations.
Mom and Dad are smashed and Uncle Lou has a lamp shade on his head. Quick let's do this like a Bar Mitzvah and grab all their beverages

noun, singular. Similar to a body shot; The skin of a penis is pulled over the head, creating a cylindrical enclosure. The inside is then filled to the brim with alcohol, and consumed like a traditional shot by a classy woman. After completion of the shot, everyone in the room must yell MOZZLETOFF!
The Bar Mitzvah: "I gave out so many Bar Mitzvah's last night that my penis has a hangover."
