Coitus Mammaris

(kō'ĭ-tes - mam-uh-res) n. adj. Sexual union between a male and a female involving insertion of the penis between the breasts. Usually accompanied by rhythmic movements, leading to the ejaculation of semen from the penis in the region between her cleavage, neck and chin. A high-brow description of a sexual act also known as "titty-fucking".

Coitus: Origin, Latin, from past participle of coīre, to copulate.

Mammaris: Origin, mammary 1682, from French mammaire; from Latin mamma "breast," probably from the child's word for "mother."

So Biff. How did it go with Muffy last night?

Fairly well, old chap. Muffy said she was in her "scarlet phase". So, after the cotillion, we did a little coitus mammaris in the back of the Bentley behind the clubhouse. I was a tad annoyed when she used my ascot to clean her "pearl necklace" off.

Coitus Mysterioso

Drunken sexual encounter where coitus may or may not have occurred.

Charlie thinks he had sex with this girl a few weeks ago, and she was begging for it, but he's never had sex with her before, or after, so for now it's classified as a case of coitus mysterioso.

Rigor-coitus

The act of making love to a long lost love or spouse after they have died. Possibly in a scenic setting like in front of a fireplace or at a grave yard. This is not to be confused with necrophilia because it embodies the love that one may have once had for said corpse.

Walter: Where were you last night Howard?

Howard: I was just really depressed thinking about Emma's passing, i had to go down to the cemetary and have her one last time...

Walter: Sometimes rigor-coitus is the only way to relive the passion you once had, I'm sorry Howard, one day soon you'll be able to join her again...

Howard: Yea, i was thinking next tuesday possibly.

coitus

Scientific reference for 'doing the dirty', having a 'no pants dance', or advancing courtship. Coitus is commonly used in a popular TV show, The Big Bang Theory.

Penny: *opens door* "Hey, my power's out, can I stay here for the night?"
Sheldon: "Do you really-"
Leonard: "YES, of course...th-that's what friends are for, after all. Lending a room in a time of need."
Sheldon: "Well...as long as this doesn't end up in Leonard and Penny taking part in coitus, I guess I can live with it for one night."

coitus interruptus

In Latin a form of birth control, the deliberate withdrawal of the penis from the vagina at the point of orgasm to prevent conception.

The practice predates the invention of condoms and was messy as the female's stomach was sprayed with sperm.

Caesar's sperm was spilled on Cleopatra's belly when he ejected his penis at orgasm.

Coitus Avoidus

Closely related to the cock-block (cockus-blockus). Occurs when you are trying to solidify a possible sexual encounter, only to be stifled by either the conscious or inadvertant action of a third party. Quite often, the offending third party is a friend who wants to subvert your sexual activity.

I was at a party last week dancing with this really cool girl, when all of a sudden out of the corner of my eye I saw Steve coming in for the kill. Steve got in between this girl and myself and started telling her I had a girlfriend, even though I don't. He also told her that I was a born-again Christian, and she shouldn't be tempting me with her sex. It was at that moment I realized Steve had served me up a clinical case of coitus avoidus.
