All mouth and trousers
The origin of this delightful expression is thought to be the north of England during the latter half of the 19th century but no one knows for sure. It is an expression used mainly by women to describe an overly pushy, obnoxious type of male. The mouth part denotes boastfulness or hot air, while the trousers part refers to obvious, unsubtle, sexual bravado. The expression gained fresh popularity during the latter part of the 20th century thanks to the BBC (British Broadcasting Corporation) television series Last of the Summer Wine in which it was re-introduced to a wide television audience.
