Nunga Nungas are a term used for breasts in a book series about Georgia Nicolson, written by author Louise Rennison. Breasts are called Nunga-Nungas originally by Ellen's brother because of the noise they make when you pull down on them and then let go.
As I was going out my bedroom door I remembered my nunga nungas. Perhaps I should take some precautions to keep them under strict control Maybe bits of Sellotape on the ends of them to keep them from doing anything alarming? I'd like to trust them, but they are very unreliable.
