!!!!1 

Element of punctuation used by morons in place of the period, the full stop, that little dot near the L key. Note: one exclamation point is usually one too many. If you do plan to use more, please take care that you retain muscle control over the finger holding down the right-hand shift key. See also gay speak.

1% 

A segment of the population (and originally the biker population) defined by behavior that is morally incomprehensible to most people. A common (and by some accounts required) 'feat' to earn "%1" designation: To have eaten a woman out while she is on the rag.

Also, refers to the known killer(s) within a biker gang by it's members. Though this is falling into disuse.

1%'s most common meaning is simply "crazy", with the specific connetation of an unknown hidden deeper direction of the one who is 1%.

"No way should you deal with that guy, he's 1%"
