Noun.
Pronunciation: just like "bahoonies" (ba-HOO-nees).
Definition: A very important piece of male genitalia that consists of the scrotum, which holds and protects the inner testes. Also, the testes themselves.
Although pronounced the same way, bahooneys is not to be confused with bahoonies, which refers to a large set of female breasts (tits, gazongas, knockers).
The term used on RuneScapeinvented by RuneShark randomly to recieve unique drops and other good stuff. Still based on luck, but still very commonly used.
