Only ever used in negative contexts, generally 'to not have a razoo,' but also 'not worth a razoo,' 'not get a razoo', etc. Contextually referring to a low value brass coin, the origin of this term remains a mystery despite many guesses over the years. Needless to say no such coin ever existed. Also commonly a 'brass razoo', and formerly spelt 'rahzoo' or 'razzoo' though only rarely AUSTRALIA, 1919.
