"Mosha's" are often seen as dirty, rude, gay/bi, an apparently their mum's get fucked reguarly by chavs, these are not true, most "mosha's" are not like this, and people who take pride in the sub culture they belive/follow will not call themselfs "mosha's" usually they are punks, goths, cyber goths, skinheads, indies, skaters or some bmx'ers which are proud to follow that exact subculture and do not want to be labled as a "mosha" often "mosha's" do not find the name offensive and it sounds rather silly.
