Ninety-sixer

A sexual position where a man and a woman lie back to back, with their heads at opposite ends of the bed. With none of their sexual organs are even remotely lined up.

It is favoured by people with strong religious beliefs.

Yo man last week at bible camp I had a hot Ninety-sixer with Rach. Had to go to confession afterwards, but Geez it was worth it.

I hope Jesus wasn't watching.

Level Sixer 

A mythical creature, the level sixer rises above all known facebook stalkers. Pastimes include stalking people on facebook (duh) and feeding off of the souls of unsuspecting human beings.

It is alleged that a creature more terrifying than the level sixer exists in the facebook world, but nothing has been documented so far.

Guy 1: dude, she's always on facebook! that's like level 6 status right there.
Guy 2: a level sixer?! naw man that's impossible...

Sixxer Boys 

A group of riders, usually squids, on two or more yamaha r6 streetbikes. They are known for revving up the engines when completely unnecessary, popping small squid-like wheelies, and attempting to stoppie. These riders are always looking up to their big brothers on the R1's..

Look at all those sixxer boys sitting at taco bell, damn squids.
