1. "Pwned" is a variation on the word owned and means something to the same effect but to a worse degree. Pwned came about as part of 1337 because "P" comes after "O" in the alphabet (and on a qwerty keyboard) therfore to be "pwned" is worse than being "owned". Contrary to what many beleive, this is the true origin of the word.
In 1967 the main guy off of the A Team (Hannibal?) found some plutonium in his jeep and he sanded it down and made it into the shape of a gun, which he fired often, but never actually hit anyone with it. Face and B.A. got in a fight over who got to hold it while Hannibal guy smoked his huge ass ceegar, until Murdock shouted out,"if you guys dont give me that Palm Wielded Nuclear Energy Device I will come over there and act all crazy RIGHT IN YOUR FACES!" So they stopped fighting, because they didnt like it when Murdock went crazy. They got dominated. They got owned. They got PWNED!
pwned means to be owned like a punk
this is the actually meaning of the word.
mainly used in internet multiplayer games. and by people who claim to be part of the 1337 .. when they are actually losers looking for an excuse to say they are better than you
