1. Someone who is overly-emotional, usually in a negative way
2. Chronically and outwardly depressed
Someone can be called emo if they have at least two of the following qualities: always dress partially or fully in
black (because it "reflects the color of their
soul"); wear very tight and restricting clothes (constantly in contact with the
skin, because they are usually deprived of any physical contact with other
people such as hugs); seem to talk mostly about how
sad, unfair, or hopeless their life is; cut their own wrists; or attempt to express their emotions through excessive amounts of boring dark art or poetry (also includes music).
