A slappachino is a young girl, often from East London, who can be found around the local branch of Starbucks on a Saturday afternoon touting for free fags and a quick shag before H&M's close.
Sharon is a thick bitch, a right slappachino.

Mike was sure he would score tonight, the club was full of slappachinos.
