It's very simple really - the OP did a decent job. A minger/ munter is hanging, rough, wouldn't touch her with yours mate. Often fat, not necessarily so. Will definately sleep with you, provided the ten pints necessary to do so have not caused brewers droop and saved you from yourself.
Chavs are common and [censored] and often have babies that they push around supermarkets while smoking. They like Burberry, spangly things, Malibu (the drink, not the beach), football, tracksuits, zooped up but still crappy cars and the people that drive them (other chavs). They go on holiday to Greece and get their breasts out in bars. They wear pink tops on Saturday nights that ride up over the course of the evening as they drink more Malibu and reveal a slightly overhanging stomachs. Most of them do in fact ming, but may or may not shag you. They tend to stick to their own species. They also like having loud arguments with their chav boyfriends in shopping malls.
Pikeys nick stuff, like Scousers.
Tarts are like nice versions of slags. Usually older. Not necessarily pejorative to call someone a 'dozy tart'. Can be a term of endearment in some circles. Unlike 'slag'. Calling someone a slag is not good, especially if they are one. Depending on how much of a chav they are, they might kick you or throw Malibu at you. Both slags and tarts have probably made a few trips to the GUM clinic, but tarts have a sense of humour about it. Slags are just, well, slags.
Easy.
