oof

Definition

Slang

  • noun a promiscuous or sexually willing female. One of a set of terms in use among male City traders, recorded by psychologist Belinda Brookes in the Independent on Sunday, 9 July 1995. Others included mum and dragon. The word may imitate a gasp of desire, like its 1920s’ predecessor, ‘oomph’ (an archaic term for sex-appeal).
