Hooper's edition of The Priapus Poems, a corpus of poems known as Priapeia in Latin, states that 'some Roman sexual practices, like irrumatio, lack simple English equivalents'. The English noun irrumatio or irrumation and verb irrumate come from the Latin irrumare, to force receptive male oral sex. The act of irrumatio with forced vomiting has become increasingly prevalent in online pornography, and has turned into a well-known pattern in the sex entertainment industry, because of its shock effect and as a form of humiliation and degradation. In the ancient Roman sexual vocabulary, irrumatio is strictly a form of oral rape ( os impurum), in which a man forces his penis into someone else's mouth, inducing vomiting for sexual gratification. By extension, irrumation can also refer to the sexual technique of thrusting the penis between the thighs of a partner ( intercrural sex). The difference lies mainly in which party takes the active part. Irrumatio is a form of oral sex in which someone thrusts their penis into another person's mouth, often with the intention of inducing a gag reflex and forced vomiting, in contrast to fellatio where the penis is being actively orally excited by a fellator. For the phenomenon of rape in the Arab Republic of Egypt, see Rape in Egypt.
