Okay, time for me to dissect this thread into pieces, yielding a result.
Let's look at Emo's and Chav's in a more in depth sense.
First of all, descriptions.
Emo
-----
Tends to listen to punk/metal/hard rock music, as well as the most depressing selections of indie.
Hair fringe typically flicked across one eye.
Nails & Hair are usually purple or black.
Clothes - usually dark, tight "skinny" jeans, and Converse's for shoes.
Can be depressing at times. MAY (May Not) harm selves with sharp objects, aerosols & solvents. etc
Tends to be apathetic towards religion, society, popularity, politics.
Most are sociopaths, some are not.
They're never annoyances, they keep themselves to themselves.
Chav
-----
Clothing is varied. Wear baseball caps tilted upwards and hardly sitting on their head.
Usually wears a cotton tracksuit, Cabrini, Adidas, Reebok, Umbro, Kappa, Nike, all that chavvy crap.
Lives in a low budget council estate.
Shortens talking, both Instant Messaging and day-to-day vocal conversation.
In ova wordz, if i woz a chav init, i wld b talkin lyk dis instd ov ritin lyk a nrml ppl innit blud.
Wen we tlk lyk dis u av 2 reed wot we say lyk 50 tyms ova lol pmsl.
*PM me for English Translation.*
Chavs tend to drink nothing but Beer and Jack Daniel's.
They refer to women as "Birds". Despite the fact they lack the wings and other typical features of your average feathered friend.
All jewellery is gold (well, it's actually that cheap 0carot gold jewellery you buy from Argos for £9.99)
EVERY CHAV OWNS ATLEAST 5 ITEMS OF CLOTHING THAT ARE BURBERRY.
Burberry =

Curse / Swear words are used more than once in every day-to-day sentence.
Their cell / mobile phone is on Pay As You Go. Usually Orange Network.
Typical research indicates their phone is a Nokia.
Constantly being brought in by the police, throwing bottles, verbally assaulting members of the public, shop owners.
They listen to Hip Hop and RAP as if it's a fashion statement.
Now let's look at the Pros and Cons.
Emo Pros - Their girls are usually f'ing HAWT <3
They don't bother anyone
They dont lurk in the streets and council estates intimidating you to the point where you don't want to 'hang' in your own neighbourhood.
Cons - The guys that wear the 'skinny' jeans look kinda gay.
- They self harm, which is uncalled for, but they see it as necessary.
Chav Pros - Clothing firms such as Burberry and Carbrini achieve excellent business figures.
- Corner Shops and Off Licenses can sell their beer.
- They provide Argos with the sales needed to keep their gold plastic jewellery in business.
- They're keeping more and more people off the streets every day, causing less litter in public.
- Chavs themselves make up for the litter decline, keeping the Waste Disposal and County Council in business.
Cons - They look ridiculous.
- They sound pathetic.
- Their houses are stains on the underwear of England.
- They demean everything we stand for.
- They make normal people turn emo.
- They keep us in our homes.
- They make us want to leave the country.
- They vandalise...everything.
- They have faces that you just want to flatten.
You don't need me to spell it out.
Emos win, hands down.
