One 

The loneliest number that you'll ever do :D

One

One is the loneliest number that you'll ever do
Two can be as bad as one
It's the loneliest number since the number one

No is the saddest experience you'll ever know
Yes, it's the saddest experience you'll ever know
`Cause one is the loneliest number that you'll ever do
One is the loneliest number, worse than two

It's just no good anymore since she went away
Now I spend my time just making rhymes of yesterday

One is the loneliest, number one is the loneliest
Number one is the loneliest number that you'll ever do
One is the loneliest, one is the loneliest
One is the loneliest number that you'll ever do
It's just no good anymore since she went away
(Number) One is the loneliest
(Number) One is the loneliest
(Number) One is the loneliest number that you'll ever do
(Number) One is the loneliest
(Number) One is the loneliest
(Number) One is the loneliest number that you'll ever do

Part of 1337 speak. Used by jackasses who want to show that they didn't forget to push the shift key but are using 1 instead of ! just to piss people off.

One 

A alternative to the arbitrary 1-10 rating of women...a woman can either be a one (acceptable to sleep with) or a zero (unacceptable)

"what happened to you last night?"
"You didn't see the blond"
"NO...was she hot?"
"well she was a one, if thats what you mean"
"Oh...I see"
