Fangus is a pungent, clumpy substance that looks and smells quite disgusting to the average westerner. Certain cultures consider it edible, but none find it appetizing. It is only eaten by outcasts or by those who have little else to eat. However, a few affluent people still eat it despite its nausea-inducing flavor, to the dismay of more civilized citizens.
