Zark off.

Zark is an expletive interjection referencing the prophet Zarquon. It is a shortened version of the prophet's name, typically uttered in anger, surprise, or frustration, though sometimes also with humorous intent.

Various expletive phrases using this slang word exist, including: "for Zark's sake" and "zarking fardwarks". Zarquon's full name is also occasionally used as a form of expletive - and in phrases such as "Zarquon's knees" - however these are seen as somewhat outdated compared to the shortened form, with Ford Prefect seeming unfamiliar with Zaphod Beeblebrox's utterance of: "Holy Zarquon's Singing Fish" on one occasion. In the radio series, "Holy Zarquon's Singing Fish" was the password to get into The Well of Urd.

  • This semi-euphemistic swear word has clear comparisons to British expletives and exclamations. It is used both as a substitute for "God", or another deity, and "fuck", or a similar curse, with the first letter being capitalised when being used similar to the former, such as: "for Zark's sake".
  • Both the use of 'Zark' and 'Zarquon' as expletives only occurs after the prophet Zarquon has been introduced, presumably for the listener's benefit of understanding the origin of the reference.
