Originates from ancient, Britonic folklore, in which tales are told of a brave warrior, cruelly slain by the evil wizard Tequilladon. The warrior's final words before his unsightly demise were "T'ees it ovah". The warrior's name was Scoatt, and he was scoatted.

He was near enough scoatted after that last vodka and coke.
