your “hoo-hoo dilly”
your “cha-cha”
your “bits”
and my favorite, your “situation”

I also really like the Vagina Monologues’ “coochie-snorcher.” It sounds like a Dr. Seuss character. :*)

Personal favorites are twat and mushmallow.

I was raised by a doctor and a nurse who started me on the facts of life with a pop-up book around age 5, so I’ve never been reluctant to use precise anatomical terms when appropriate (e.g., with my doctor). In casual conversation, of which there is a surprising lot, it’s “vajayjay,” “vaj,” “girly parts,” “ladybits,” or “down south” (particularly when discussing a man’s willingness or reluctance to head there), and my new favorite term is, of course, “baloney rose.” I’m also amenable to “pussy,” simply because it’s warm, furry, somewhat standoffish to strangers, and friendly when petted.

Sex, while mid-act, tends to be “having sex” or “making love” or “fucking,” depending on the partner and the circumstances. In discussion, it’s any of those, plus “shagging” (my favorite), “getting horizontal,” “bumping uglies,” “scrogging,” “boinking,” “tapping” (as in, “I tapped that,” which I find appropriate for either partner), “hitting it” (ditto), “boning,” “churning butter,” “sharing bodily fluids,” “getting groiny,” “waking the neighbors,” “making the baby Jesus cry,” and “pointing my heels to Jesus and thinking about handbags,” among others.

Baloney Rose. Which my husband finds hilarious.

Oh lord. That’s a new one to me and it cracked me the hell up.

So, forcing people to re-set their responses is a bit futile really IMHO.

“If you’re lucky later, my Kraken will take down your pirate ship.”

Ok, so that’s a more extreme slang term. I’m a fan of the straight-forward vagina, sometimes cunt. I hate coocher and pussy.

For sex, my boyfriend and I fuck or have sex or “play Scrabble.” The latter can lead to interesting conversations. We’re in a long distance relationship so I sometimes have a Facebook status of “Lindsay is wanting to play Scrabble badly right now.” My well intentioned friends bring over a Scrabble board and offer to play, and well, I’m a Divinity school student so they’re not big on the premarital sex so telling how I’m sexually frustrated isn’t quite as appealing for them.

[US and UK vulgar slang]: The female genitalia, especially the vulva.

When I first got to uni, a popular euphemism for sex was “romping”. It seemed to drop out of use shortly after, which is a shame, because I think it describes the recreational nature of the event beautifully.

“I do use a lot of euphemisms for sex, boning among them. But I find I use them very indistinctly; as in, without regard to whether there is penetration or who is penetrating whom.”

I use boning, screwing, fucking etc this way too. The idea of only using the words to refer to the partner on top never even occurred to me until I was talking to my friend and saying “so I was fucking Dude X” and some guy interrupted me to say “no you weren’t”. In the middle of a bar. I was pretty drunk at the time, but according to my friend I turned around and went “um, excuse me, but I was there, I’m pretty sure I was fucking him” and he then proceeded to explain that this was impossible due to my being a girl.
He was a bit upset when the friend and I started laughing.
