Gammer is someone who is hideous to look at. Mainly [teenage] female [chav] types from London that used to use this phrase in the mid to late 1980s, to describe an [unattractive] boy.

It was believed to have originated from the [pale], [pink], [pasty] flesh of a pork [gammon] joint. Also termed as [gammer-chops]. Chops which is a slang term for the face.
