http://en.wikipedia.org/wiki/Pwn

Etymology
The most widely held theory is that pwn originated from a typo in first-person shooter games, the common mistake occurred from a hand position. The user, using his mouse right-handedly, would hold three of his fingers on the keys, "a", "w", and "d", along with the mouse in his right hand. When prompted to make a comment upon fragging his opponent, a quick motion to type the word owned resulted in a typo. Due to the proximity of the keys "p" and "o" on a standard QWERTY keyboard the user hit the "p" instead of the "o" key, resulting in the word pwned. Intentional misspellings based on keystroke errors are common in leet, such as teh for the and replacing exclamation points with 1s.

It's even worse when you hear people say it.
