wanker

Definitions

Slang

  • noun a masturbator. For the probable etymology of the word see wank.
  • noun an inconsequential, feeble, self-indulgent or otherwise offensive person. The term of abuse or disapproval (most frequently applied to males) has been in use since the early 20th century, but became extremely common in the 1970s. In the USA the word is known, but its force as a taboo term in Britain is often underestimated by American speakers.
