Chavs: In gangs, mostly white, talk in slang, usually people who think they're scary as fuck, but are actually looked at as pathetic and weak, overly patriotic, most likely racist, don't look like they've showered in a billion days, usually have bad breath from smoking and drinking, probably dropped out of school early, usually brick layers, have kids early/increased rate so they can get child support from the government, if they're not brick laying, they're either drug dealers or just unemployed alcoholics, also getting money from the government, usually have a Rottweiler dog to make them look more intimidating, wear tracksuits and knock of Nike and Adidas, probably live in a shitty council house/flat/maisonette, probably have a stolen moped or ride a stolen bicycle everywhere, hang out near/outside of corner shops, probably sleeping with 14 year olds because they "look older than they are!!1!!" so that's somehow justified...I could go on.
Roadmen: "I am you, but stronger." Version of chavs, mostly black people, are actually a bit more intimidating, have legit sports clothing but it's most likely purchased with money they've earned illegally, chavs wanna be them, probably also live in a council provided home, to be fair, they're mostly either employed or are enrolled in college...that's it??
