Chippie? Chip shop? Employee of same? Girl of some sort of repute, ill or otherwise?

I know a chunk of the song, and political correctness is not something those who sing sea music (or those who hang around with them) are overly concerned with. No 'N' words, though. Marsden's song is a little insulting to Chinese people who own food establishments, but much more so to drunk people, people from Manchester, and possibly dogs.
