twelve tens

Well i'm not entirely sure to be honest. It's presumably derived from technics 1210, the Ford Sierra of decks used by every DJ from fatboy slim to the fatboy slim wannabe running your local church under twelves' disco.

The phrase has been popularised by irish Sp'o'iral in the UK big brother #7 in reference to wannabe ghetto princess Aisleyene (sic.) and some part of her body. She does have big fakes boobs and shows her ass quite a lot, so i guess it's one or other of them. Look at the example and see what you think.

Ais's got the twelve tens going on and i want a sl'o'ice.

Sl'o'ice being a irish internation of slice, as in her ass is like her loaf of bread and i want a sl'o'ice. (his phrase, not mine.)

twelve days of christmas 

For twelve days, starting on Christmas Day, you masturbate the number of times that correspond to that day. For example, on Dec. 25, you masturbate once, Dec. 26, twice, until twelve days after Christmas, when you must masturbate twelve times in one day. Consider yourself to be a true man and have balls of steel if you complete this task.

I tried to do the twelve days of Christmas, but by Day Eight my dick was black and blue and about ready to fall off.

Twelve o'clock 

Name given to girls with 10/10 asses but you never see their face. Commonly used when you and your buddy are walking behind a fine ass and you casually call out 12:00 to signal your bud.

Matt: Hey Zach, 12:00
Zach: fucking hell twelve o'clock is ahead of us again
Matt: I want to see what she looks like
Zach: That would ruin the magic of a twelve o'clock
