The cat that always seems to show up, purring, whenever you have a boner, and proceeds to watch you have sex, receive a blow job, masturbate, etc. (Includes NARBs)
You: Oh look, there's the cat watching us again.
Your wife: You know we can't have sex without our beloved boner cat present.

Cats (cool people) that walk around with boners all over the vases, and break the fine china.
A Boner Cats just walked through my home and destroyed my very expensive three-dimensional art. :(
