Emo
From Superdickery
Emo, short for emotional, is a name for chronically depressed kids. Known for brooding, cutting themselves with razorblades, and listening to Linkin Park.
A recurring point of humor on the Superdickery forums, and on the internet as a whole.
Chronic depression is not a joke. Emo kids are people who act depressed because they think it's cool.
