Completely, utterly, and totally inebriated to the point at which conciousness is a long forgotten sensation.

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.
