Select quotes:
Emo is a somewhat ambiguous slang term
The term's definition is the subject of debate. Emo is now often used to refer to a person's fashion, personality, or both, as well as a musical category.
most definitions of emo hold that an emo person is emotionally candid, sensitive, shy, introverted, glum, and quiet
Members of the emo subculture are portrayed by critics as melodramatic, self-pitying teenagers who pour their efforts into writing bad poetry and spending a great amount of time on MySpace.
The current emo subculture has been called a "sad caricature" of what it once was.
The backlash against emo has become so prevalent that it may itself have become a cliché: one commentator notes that "hating emo kids these days is as hackneyed as emo itself."
