Those pricks that wear random combinations of clothes to look "different", yet they look stupid. These are the guys that say how they're indie and going against the stream, but buy their clothes from high-end labels. They just buy the raggy looking high-end clothes and put them together in terrible combinations. Then, they top it off with some neon colours, and a stupid hair cut.
In other words, Hipsters. I hate them, and they're always around my University.
Also those "coolio" guys, who dress in that shiny sports stuff, like sweats and jackets, and spike their hair up (nothing wrong with spiking it tastefully, I do it, too a bit), and sit on the bus with their legs spread wide. Ugh. One time one of them got on my bus with those button-up sweats and I could see his hairy legs between the cracks! Disgusting.
I think these guys are known as Guidos or Wiggers.
