Being oik-ey. Not meant as a snobbish statement - it's a choice to behave in a brash, ignorant, crude way.
I mean: crude language, bad manners, being thick/ignorant and proud of it, regularly drinking lots of pissy beer and burping, ignorant attitudes, chip on shoulder, stereotypically predictable obsessions (sport, cars,) and objectifying women.
Ooh - and those horrendous cropped trousers, gathered at the shin with drawstrings/toggles.
Enormous trainers. Actually, trainers in general - they are so cliched (unless you are doing sport at the time) and make me think of smelly feet.
