Originated a conversation with my 13 year old sister, who claimed that at her school (Newstead Wood), people were either "slags", "neeks" or "all right." Or they were neeks who were also slags- a common stereotype of the Newsteadians, perpetrated by people lacking two brain cells to rub together. I then started to jokingly call her a slag as per usual, then the wondrous juxtaposition of a word struck me- sleek. Someone who is both a slag AND a neek. I rather like it.
That girl's such a sleek, did you hear about her and her lab partner?
