A bunch of fives

To punch someone

The idiom is a slang term and originates in boxing terminology. ‘Boxiana’ (1821), a classic work on the history of boxing by Pierce Egan might contain a reference to the term (but this is unconfirmed, as copies are difficult to find today). In the 1800s, boxing was a common form of fighting. In 1825, the phrase appears in Charles Westmacott’s ‘The English Spy’: ‘…came up to the scratch and floored many a youkel with their bunch of fives.’
