Cockney rhyming slang - round the houses

This seems to be a strange bit of rhyming slang but it exists, so ner. 'Round the houses' are trousers. Apparently there is also use for 'round my houses' which probably makes even less sense, but is oft shortened to "round-mees".

Fun fact: Trousers were invented in 1934 by Noel Coward and here he is wearing a pair.

Trouser wearing Noel Coward.
