Originally dates back to the days of WarCraft, when a map designer mispelled "Own" as "Pwn". What was originally supose to be "player has been owned." was "player has been pwned".
Pwn eventually grew from there and is now used throughout the online world, especially in online games.
So lets stop using this stupid word because it's for children

Instead of: You've been pwned
You have been fucked or You have been smoked. thats sounds more professional doesnt it? lol
