(Verb) A command in the game Soldat. Pressing / and then typing pwn will make said Soldater hump into the direction he is facing. Normally used against a player who has gone Away From Keyboard. Amusing. A few Soldat porn pictures have been made using this. They usually depict one soldat lying down with his head up, whilst the other Soldat performs '/pwn' in front of him, ammounting to a blow job.
Going up to an unsuspecting player, and /pwning them from behind. Can be very funny when done against a campingsniper who is in zoom mode.
PWN (verb) 1. An act of dominating an opponent. 2. Great, ingenious; applied to methods and objects. 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.
Like the cracker usage of own, only more so. Can be used as an verb, adjective, or possibly even a noun (although pwnage is more suited to use as a noun).
Pronunciations vary; "pone" is favored at the 3drealms.com forums although I personally prefer something like "pwun" or "pw'n" (preserving the "w" sound).
v: Haha, I just pwned you at UT2003!

n: Another excellent pwn by R4nd0md00d134!
