It's ª smªll 'a' rªsied in the ªir. Nobody reªlly knows whªt it's for but it mªkes you feel speciªl to use it, just becuªse n00bs will wonder how you typed it.

<no_one_2000> Dude, what is this ª character? It's in the ASCII chart but nobody ever uses it.
<fyrehart> No clue.

120d

See 5 and 120 for an explanation.

calkfreak83: Just to make things weirder, we should start saying "120d".

120d = "LOL!", just use 120d in replacement of it.

Nothing is compatible with a Mac! Not even viruses! 120d

shitfaced cocksucker

Combinations of curse words are typically used for insults when angrier than usual. This one, for unknown reasons, sounds better than most others and continues to be used by many in random explosions of anger.

<fyrehart> I am a shitfaced cocksucker!
<no_one_2000> Yeah, you are.

dot^3

A clever way of denoting an ellipsis (those three dots "..."). It's commonly used after an idiot makes a stupid remark.

<tehn00bz0r> hey wat iz teh numbar for 911?
<Scr33nName> dot^3

!##&

"1337" typed with the shift-key pressed. Seen most commonly from n00bs who type in all caps (but are too stupid to use the caps lock key), or by those making fun of n00bs.

<n00b> OMG HOW U KIL ME U MUST B !##&
<me> Stfu, n00b.

5

5 is an elite, nerdy way of saying "LOL" See 120.

LOL means "Laughing out loud" and is a common acronym used in chatting everywhere.

LOL (or lol), written in 1337 is 101.
101 in binary is equal to 5 in decimal.

So, LOL = 5

OMG, your computer has spyware? 5

pzwn

Pzwn is the "ghetto" version of pwn, a word which I'm sure all heard used before in online gaming or on IRC. Pwn -> Pizzwn -> Pzwn.

"Unreal Tournament is so awesome, it will pzwn you."
"I pzwnd j00!"
"Mike pzwnz me"
