Whatever google answers people come up with, the fact of the matter is by and large in Ireland Knacker is a derogatory word for a Traveller, yes it's also used to describe someone you think is scummy or smelly or whatever but that comes from saying they're as bad as a knacker. It is a slur on a minority group in Ireland. Having said that I also think Harry has been xenophobic towards Marc with her Irish **** comments and mocking his accent. Both horrible bastards imo
