Superlative of pwned, gaming
vernacular. What happens when one utterly humiliates one's opponent to an extent not thought physically possible. For example, at Magic the Gathering, trashing somebody on turn 3 or earlier thanks to utter skill and/or a miseworthy opening hand is an example of qwnage.
Note - Sometimes it is pronounced "Quoned", but I prefer to
think of it as "Quooned."
