Reverse Birth Girth

(adj) Having a shaft and meatus so thick, insertion into a vagina (or similar orifice) is akin to childbirth, but in reverse.

Last night at the bar, I met a guy named Tyresius. Drinks and conversation flowed. One thing led to another and before I could say clitoris, I was being ripped by Tyresius' reverse birth girth. Ooo-la-la. Ouch.

Reverse Birthing

A specific act involving a midget, a woman, and a 100-foot slide-and-slide. The woman lays back at the end of the slip-and-slide with her legs wide open. The midget then is slid down the slip-and-slide at a high speed, resulting in the midget sliding all the way down the slip-and-slide, and going so far into the woman's vagina that it ends up entirely inside of her, resulting in what looks like a birth in reverse (hence the name, reverse birthing).

The festival ended with a complete reverse birthing. It was epic.

I've got major chafing down there from John's hair when he did the reverse birthday on me yesterday.

Reverse birthday present

Instead of giving a gift to someone on your birthday, you expect a present instead from them.

atareh: "Devon, I know it was YOUR birthday last week, but you should still get ME something. Think of it as a reverse birthday present"
