prenatal fuckup 

An extreme disappointment, who's foolish mistakes trace back to before they were were even born.

I would have never screwed your mother in the first place, if I had known what kind of prenatal fuckup you'd be.

preNatal 

A time before Microsoft's Project Natal was revealed. Referred to as a simpler time by many as we didnt have to get off the damn couch to play a game.

Guy 1: Dude! look at this old game controller!

Guy 2: Woah! It has buttons and you have to hold it!

Guy 1: Yup, this right here is some ancient preNatal technology.

Guy 2: Gotta love the good ol' days.

peristalsis 

Rhythmic visceral muscle contractions in the digestive system that function to transport ingested materials caudally, unless stimulated by the emesis reflex where the flow of digested material is reversed.

Dude, last night Veronica's peristalsis was inhibited by my massive cock.

reverse peristalsis 

An inaccurate alternative term for regurgitation or vomiting, typically used by grade school science teachers who don't actually understand science and use the urban dictionary instead of a competent textbook to source classroom material.

While reverse peristalsis in the small intestine can occur during vomiting, the actual act of vomiting does not involve peristalsis.

The technical term for vomiting is not reverse peristalsis it is regurgitation.

prenatal suicide 

an alternative term for a miscarriage.

"Wasn't she pregnant?"
"Yeah, but the fetus committed prenatal suicide."
