Take a 1.5

The act of taking a piss out of your ass, usually after a night of heavy drinking. Its a combination of taking a #1 and #2 out of your ass at the same time.

Damn, I drank too much last night and now I gotta take a 1.5.

The 1.5

An impromptu defecation involving an individual (esp. male) who chooses to urinate in a seated position.

Dude, sometimes I just like to pee sitting down because not only is it more relaxing and hygienic, but you never know when the 1.5 will show up.

Mexicans do not exist. They are a myth, like Santa, the Easter Bunny, or the Tooth Fairy. They are just something your mother tells you are real when you are little.

You will go into extreme stages of denial after reading this definition. Go seek therapy, you'll need it.

Adrian: "Hi, do you want to come to my house? You will meet my Mexican mom."

Daniel: "Rule 1.5"

Adrian: *extreme stages of denial*

Xbox 1.5

The name given to Xbox 360 by people who fall in one of the following catagories:
1) They are cranky because their favorite company doesn't release their next-gen console for another year or more.
2) They have never seen a trailer for ANY Xbox 360 game.
3) They were stupidly and completely faked out by the entirely prerendered trailer for the PS3 game Killzone 2.
4) Lack the brainpower to count to 360.

Xbox 1.5, hee hee, I'm so bad. <I wish I could count past 7> :(
