Most cultures have two levels of swearing—relatively mild and highly profane. Ashley Montagu, in The Anatomy of Swearing, cites a study of swearing among the Wik Monkan natives of the Cape York Peninsula. They have many insults which are generally regarded as harmless teasing—big head, long nose, skinny arms—and a whole body of very much more serious ones, which are uttered only in circumstances of high emotion. Among the latter are big penis, plenty urine, and vagina woman mad.
