1337 Speak has many different contributers to it. Alot of its being a way to get around banned words in chat / forums. Another place is online gaming- i mean gaming like counter strike / or RTS games. This contributed words like pwnd, ownd, woot, n00b, etc.... The reason for these abbreiviations is that you only have a like 3 second timeframe to gloat over your kill, else you get taken down in the next game, or lose a vital strategic advantage. Thats why you say \"pwnd\" instead of \"Woo hoo i beat you so much that time you suck\", and expressions like \"woot\",. etc. I undedrstand people using it in those situations, but outside of that its just stupid.
