9 percent

The amount in a child's lifetime (up to 18 years of age) that they spend in the education deparment being schooled, high-schooled, home-schooled or tutored.

Whew, the whole of my 9 percent was wasted in that hellhole.

Aisle 9

The point where a person has a great loss of mental and motor skills due to consuming copious amounts of drugs. Aisle 9 is the place where feral folk reside.

"I am so fucked up," says Hi-Meh. Temmy resoundingly concurred and stated, "Aisle 9 has arrived!!" To which Hi-Meh replied, "I'm fucking rollin'. But that's to be expected when we are on day 2 listening to Victor Calderone and you SNOML'd the shit outta me."

- Hell yeah a new album of slayer ! I love it ! 9/11 best day ever !
- Not that Bill...
