They're a cross between emo kids and chavs.
They often have emo hair style's while wearing chav clothing, or wearing emo clothing and having hair which appears to have been attacked by bleach and a chainsaw.
They're marginally better chavs since their pale complexion keeps them inside and their short life expectancy is also a bonus.
(Abbreviated to emok or emoch)
