When the same course of events happens repeatedly, despite attemps to to stop or change it.
Background: Expression is derived from the original Super Mario Brothers game on Nintendo. Some of the Bowser's Castle levels were 'repeating castles', where the same sequence of screen would repeate continually until the player performed the neccessary sequance of actions to get out of the repetition.
As Joe and Jon walked back to their campsite, they past what looked like the same tree at least three or four times before making it back.
"Fuck, I hope we get out of this repeating castle before dark," said Joe.
