green wee man
Our school had blue urinals. Thus, if you were standing next to someone you didn't like, you could accuse them of being the Green Wee Man. Reversy privilege prevented them from pointing out that your wee was green too. You may be called upon to piss in public - ostensibly to prove that your piss isn't green, but having the pleasing side effect of humiliation. Whether you fail or pass this test is down to the whim of your peers rather than any serious use of a colour chart.
