"Cargilling" is the act of one player, reaching 10 deaths or higher in a single game. This player is then open to ridicule, no matter how many kills he/she may have acquired beforehand.
This term originated when the infamously unskilled player known as "Cargill3", Cargilled frequently during gameplay. When the term was coined, the player then quickly changed his name to "LoklaiN", in a vain attempt to avoid ridicule.
"Aw shit, I Cargilled so hard that match.."
