Metalocalypse is an animated Adult Swim series about Dethklok, a fictional death metal band whose members are absurdly famous and dangerously incompetent outside music. Skwisgaar Skwigelf is the band's Swedish lead guitarist, known for his speed, arrogance and distinctive accent. Short clips of his lines circulated on soundboards and in fan edits long after the show's original run, because his delivery is instantly recognisable even without context. Fans still use it to signal insider knowledge of the series and to deflate overly serious metal posturing.
