A swear-word invented for use in the TV series Farscape. Its meaning is unspecified, but it is generally invoked in phrases such as "what in the yotz are you doing?".
The word-structure is presumably meant to be alien, but closely resembles words originating from eastern European Jewish languages/dialects (e.g. putz).
Why the yotz didn't you tell me about the frelling intruders on the bridge?
What the yotz do you think I'm going to do with this?
