Irrumator 

A man who forces someone to give him oral sex. Comes from Catullus, the best of ancient Roman poets, who uses this word to describe a government official in poem 10.

Stay away from John; he's such an irrumator. Last time Susan slept with him, she could hardly talk the next day because her throat was so sore.

Irrumator 

The latin word describing a man sucking another mans penis. This was considered the lowest form of sex by the Romans. A man having his penis sucked was a fellator.

Lucius Pipinna is such an irrumator.

irrumatio 

The act of thrusting of the penis into the mouth of a partner. The penetrative partner (the irrumator) engages in motions by moving his hips and body in a rhythm of his own choice, in contrast to the standard act of fellatio. A form of oral intercourse, irrumatio is commony called facefucking, skullfucking, and when penetration is deep, throatfucking.

I'm planning to get down on my knees for irrumatio with my husband tonight. I love when he fucks me in the mouth, it's one of our favourite pastimes.

irrumatrix

The feminine version of irrumator. Latin for a woman who thrusts her penis/strapon forcefully into another's mouth, i.e. in order to face-fuck them.

Marius: I've heard it whispered that Cornelia is quite the strapon enthusiast. Is it true?

Catullus: Oh, yes, she's quite the irrumatrix. Don't get on her wrong side, or you won't be speaking for a week.

Reverse Self Irrigator 

A delicate manoeuvre when one has just taken a dump and has come to a sudden realization that there is no toilet paper left. The Reverse Self Irrigator (or RSI) is when the dumpee bends his penis under his gooch and proceeds to piss into his crack, which then cleanses it. This move is exceptionally difficult for females as it requires a hosepipe or fishtank pipe in order to be performed. This can often be challenging as one must remember to block the penis whilst taking a dump in order to not lose valuable piss which will later be used to cleanse the asshole. If the dump is an afghani mud musket then you are in for a bad time.

Pat: Wow that dump was good
Mitch: How did you wipe, these gas stations never have toilet paper
Pat: No problem man, I just did Reverse Self Irrigator

Irrumabo et Pedigabo 

The 'classiest' way to tell someone that you're going to fuck them up. Latin students use the term to evoke confusion in others and also to evoke their superiority complex in having all-powerful knowledge of a dead language.

In Latin, it translates to "I will sodomize you and face-fuck you."

It can be found in the poem Catullus 16.

Kyle: "The fuck are you doing over here sitting on your thumb?"
Nick: "SHUT UP KYLE! You're always bullying me and I've had it!"
Kyle: "You're asking for it when you do stupid shit like that."
Nick: "IRRUMABO ET PEDIGABO, bitch!"
*fight ensues*
