Killjoy

People who consider themselves fans of My Chemical Romance. It's a relatively new term, emerging after the release of their fourth album, Dander Days: True lives of the fabulous Killjoys. Killjoys are often rebellious, and express their rebellion through music, art, or literature. As such, they're somewhat well-know for being artistically gifted in those and other areas. Sometimes, a killjoy will give him/herself a "killjoy name," which is usually an exciting, unique adjective followed by an equally exotic noun.

Killjoys, make some noise!

Killjoy

Someone who often spends their free time ruining the fun that others are having.

Guy 1: Dude, there's a bunch of killjoys over there, what do we do?

Guy 2: Just don't act like you're having fun, they won't suspect a thing if we just sit here and act "normal".
