Pwn comes from the word Own, meaning An act of
dominating an opponent. Originally said during the days of WarCraft, when a map designer mispelled "Own" as "Pwn", thus making history.
Chovilla comes from the name Pancho Villa. Pancho was a Mexican
Revolutionary general dating as far back as the late 1800's to early 1920's. He was a train robber and a Violent man and also raided many places.
So with that being said, Pwnchovilla is when a kid gets pwned
old school style. Pwnchovilla is when someone gets raided on or gets ganked.
