Created in 1972 by the 3rd SOG (Special Operations Group) when a Lt. Colonel Hank Munro shot a Vietnamese sentry with a Mk22 Hush Puppy. Due to the tension at the time, he inadvertantly said "pwned" instead of "Delta, move in and eliminate all hostiles." The subsequent death of Lt. Col. Munro as he charged a heavily fortified position lead to the term "pwned" being adopted as short-hand for "that dumbass just got his ass whupped in a helluva funny way."
"Did you see that car crash where 27 people died after someone swerved to avoid a cat?"
