A derogatory name for either a 'Hoe" or 'Hooker' who is unusually hirsute or hairy. Usually, unfeminine areas of hair, like the chest, face, back, or arms. It is called Bussy because of the unfeminine areas, not particularly for men only. It is also for alliteration, since bristle & bussy start with the same letter. This sort of concubine is interchangeable and not meant for literal use.
When two heterosexual males make-out after being promised that their act will be rewarded with oral sex from a female that one or both of the males have a crush on.
