You can't actually pronounce pwn in real life. The word pwn was coined in 1999 (I think) by Counter-Strike player Chris...uh, McVredremwenen. Anyway, Chris McVredremwenen was typing about how he "owned" someone, a phrase coined in 1997 by Doom II champion ...erm, Jeff...Smitty, and accidentally hit a P instead of an O. Therefore, the language known as l33t was born. The word l33t was coined in 2000 by Tim Webresdevncer.
