The leet uber way for stupid-assh4x0r to say word. Means the same thing.

10-12 is a cb-radio 10 code which means "visitors present". It was a way to let someone on the other end know to be careful on what they said. Today it can be used to warn someone to stop talking about something or to be careful what they talk about at that moment.

People who are younger than you, you call them "12".

the age at which most kids think its cool to say "thats so fucking retarded" after every sentence.claim that music is their life and have silly little relationships that never work out

Any girl that is not 18 (AKA of legal age) is automatically labeled as being 12.

Without any doubt what so ever, 12 is the greatest number of all time. it's not likely that anyone does'nt know this but for those of you who want to be reminded of just how good 12 is here... Months in a Year? Hours in a.m? some of the finest rugby players have worn 12, the number of the inside centre jersey in union. The board of friends officialy recognized this, and one of it's main aims is to spread the knowledge of this fact. In the history of the universe,only 12 things have happened, numer 3 being dinosaurs and number 11 being star wars. this isn't a crackpot theory, throughout any given day you will see at least three 12 references. Snoop Dogg's favourite number is also 12.

The combination of #1 and #2. In other words, when you have to pee and poop.
