Variation of OWN. A glitch in some nerd CPU game like warcraft where the admin or editor slipped up and said Pwned instead of Owned. Well the cpu gaming nerds decided to start a PWN saying club and now the whole country knows because nerds who PWN and warcraft have no friends so the put things on the internet. Thus, worldwide nerds will say pwned when they increase their XP in warcraft. In Halo 2 however true gamers, not gay nerds, may use pwn when they dominate some other fag in the face.
