For people who like Chavs and think they get a bad rap!
"Chavs" (aka Charvers, Charvas, or Scallies - "Chav" comes from the shortened version of "Charver") are a subculture/fashion and music sense in Britain (like punks, goths, emos, nerds, etc) that has existed since the late 1990s.
Though they are sometimes likened to "British Rednecks", anyone of any background, gender, or age can be a chav. Chavs sport a distinctive look/fashion sense - baseball caps, tracksuits, North Face puffer jackets, sports trainers, and often a gold chain that's worn around the neck (sometimes also gold bracelets or sovereign rings). They often like listening to UK Garage and the subculture is associated with a punkish attitude. If you've encountered someone looking like what I described while calling you "mush", chances are you just encountered a chav!
Though it's not as prevalent as back in the 2000's (when sites like "chavscum" were hugely popular), the British media and many people still like to demonise "Chavs". This community is for people who don't think they're all as bad as they're said to be.
