1. A mentally ill person who 'identifies' as something they are not, ie: gay or trans - who then proceeds to force others to affirm their mentally ill beliefs.

The simultaneous presence of feces, urine, and blood in the stall of a truck stop bathroom. Like other rainbows, the Truck Stop Rainbow only appears when the proper conditions exist.
