1930s: imitative.

  • Bonk is an imitation of the sound of a solid object striking a hard surface. It first appeared as a verb, meaning ‘to shell’, in the First World War. The sexual sense does not seem to have been used before the mid 1970s, but has become established, perhaps because people feel it is an acceptable term that is not too rude. The link with bonkers (mid 20th century), ‘mad’, probably comes from the idea of a mad person having been ‘bonked’ on the head one too many times.
