An Emo is a slang term that is enforced on someone by people who claim to be "cool". Real Emo's do not go round saying how much of an Emo they Are. There are Three types of Emo.
Type.1. Normal Emo.
some one who listens to music because they enjoy it and not because they think its cool. they also dont stop listnening to music just because the band has been "discovered". this type of emo does not go on huge shopping spree's at the most expensive stores to "buy" their look. they wear what they feal like and are comfortable to wear. they are not DEPRESSED, they are happy and normal human beings, they see the world as a wonderful place. its just inhabited by lost and depressed people.
Type2. Fag Emo.
This is the type of emo that gives Emo's a bad name. they go out and max out their daddy's credit card on the most expensive clothing, they find the most underground music. they can and dont even listen to it. they wear band t-shirt's even if they dont even know 3 songs or cant name the people in it.
This type of Emo is The least common. this type of Emo is one who rejects society all together and refuses to talk or co-operate with anyone who isnt an emo. they stand around and "look cool" they do things deliberatly to piss of comformists. this is the sort of emo that slits their wrists just so they can show it off.
