Establishing an Unreachable Baseline

An experience is so extreme that it makes all previous similar experiences that would have once invoked such reaction seem bland. A pale imitation of the perfection that the victim has tasted (be it literal taste or figurative).

Maybe someone heard a joke, and it's so funny that nothing else can make that person laugh. Or someone went into Land of Faerie and in typical tourist fashion, decided to try out the local cuisine and now because his standards are now so high, everything else he tastes would be like a normal person tasting sawdust, there is a good chance he considers regular food so unpalatable he will probably choose to simply starve if denied access to fairy food.
