(One of the constants from my way too many years hanging around various dog newsgroups was "Oh my god, we just got a little girl puppy and she wan'ts (sic) to make whoopee with our other dog and my husband says that means she's a lesbian???")
to make whoopee
I have never heard anyone use this outside The Newlywed Game! It makes me laugh.
We had a very demure bitch, and I can't imagine her ever doing such a thing. The freakout and the "ooh! gross!" factor wouldn't have been there with her anyway, since there's no comparable requirement to recoil from specific and enthusiastic body parts.
Ah, dogs. Suddenly I don't remember why I prefer them to cats.
Miss Dallas deffinately likes the humpty. I don't have a boy around to compare her too though.
There's an old song called "Making Whoopee." Though it's about something closer to partying than sex.
Yeah, I'm sitting here going "cat person!"
There may be humpy cats, but they are definitely the minority of the species.

You had dobermans, right? Yeah, those are some pretty in-your-face specific body parts when they get enthusiastic.
