ISMFOFian 

A person who listens to the music of I Set My Friends On Fire, or ISMFOF. In most cases, they are kind, amazing, and awesome people.

Person 1: Hey, Josh over there is headbanging in the middle of the street. What's up with that?

Person 2: Oh, he's an ISMFOFian. He's prone to random Hxc 2-Step dance fits, headbanging, and screaming out at strange times.

Person 1: I want to grow up to be just like Josh!

Josh: *dancing* HOT FLASHES, AND RASHES, I'M FEELING particulary pretenTIOUS!
