The female version of a douchebag. It has been decided that one cannot refer to a female as a "douchebag", so the opposite and equal term "cockswab" must be used when describing a female with douche-like qualities.
This ugly muffin-topped cockswab at the bar needs get her fucking ego in check! And HEY! Wasn't she wearing that same parka and side ponytail last time we saw her???
