Stupiditarded 

A term first coined by The Distressed Watcher (A.K.A The amazing Atheist) to describe the glitter skin transformation of a vampire in direct sunlight while reviewing the movie Twilight. It blends the words "Stupidity" and "Retarded" into a stronger negative adjective.

Carlos Mencia's attempts at comedy are Stupiditarded, if not an abomination.
