The stereotypical sweaty wears baggy trousers or skate jeans with a hoody or t-shirt with their favourite band's name (e.g Green Day) or a brand (Etnies, DC, Quicksilver). These are usually worn with a pair of skate shoes or converse. However,chavs use the word sweaty as an insult to anybody who likes any guitar-based music, whether it be McFly or Slipknot.
