Nyam nyam is a general term used to describe sexual encounters with epic levels of ecstatic pleasure. Used in general conversation to refer to situations of Fallatio, where the female participant expresses her gratitude and enjoyment with the phonetic exclamation “NYAM, NYAM” at or after the point of male climax . Its roots can be traced as being imported to South Africa by a Zimbabwean student and first used in late 2002 / 2003 in the balmy suburb of Ronderbosch, Cape Town. Further uses also refer to the pursuit of such sexual encounters, or the general enjoyment of sexual or otherwise pleasurable activities.
