Pwn is a leetspeak slang term derived from the verb own, as meaning to appropriate or to conquer to gain ownership. The term implies domination or humiliation of a rival, used primarily in the Internet-based video game culture to taunt an opponent who has just been soundly defeated (e.g., "You just got pwned!").
In script kiddie jargon, pwn means to compromise or control, specifically another computer (server or PC), web site, gateway device, or application. It is synonymous with one of the definitions of hacking or cracking, including iOS jailbreaking. The Pwnie Awards are awarded by a group of security researchers.
Popularity of the term among teenagers rose in the mid-2000s, with the spread from the Internet written form to use in spoken language.
Because pwn is primarily used in written form, it has no single generally accepted pronunciation: renditions include // OHN, // PWOHN, // POHN, // pə'-OHN, // PAWN, // pee-OHN, and // PWEEN. Originally, pwn and its variants were pronounced // in the same way as the verb own, the tail of the p being "silent". A notable usage of this pronunciation can be seen in the Internet distributed series Pure Pwnage (pronounced "pure ownage" / /).

- The word "pwnage" can be pronounced several different ways. The show's creators pronounce it "ownage". "'Pwn' was originally a typo of 'own', because the 'P' is near the 'O' on the leopard. The person is still trying to say 'own'." [TeamSpeak chat, December 13, 2005].
