Goblin on drums 

A type of cellar-dweller that is characterized by owning a drum set, or some other type of musical instrument, this giving him an overinflated sense of coolness. Behaviors include bragging to people about being hungover at work, and drawing undue attention to their personal appearance (e.g., "check out my sweet, sweet auburn hair!")

Wow, listen to Sean talk about how cool he is just because he plays the drums. He's such a goblin on drums, he still lives with his parents in a room that has carpet on the walls.
