peristalsis

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.

Paristalsis 

Paristalsis is defined as a potentially life threatening condition whereby excessive consumption of white bread, particularly baguettes, antagonises peristalsis and the normative operation of the lower digestive tract
Doctor: Your son's coma was induced by an overconsumption of french bread, which acted as a sort of glutenous cork obstructing the colon, rendering normal peristalsis completely ineffective. This caused a backlog of semi digested food in the stomach and small intestine that exerted a tremendous pressure on little Jimmy's fragile little brain, causing a massive stroke. I'm afraid that we are going to have to surgically remove the obstuction.

Concerned parent:Oh dear God!

Doctor: Don't worry, Paristalsis is extremely common in france and the procedure is really quite routine.

Parent: Ah, I see. Is that why Parisians often seem so braindead?

Doctor: Actually, yes.
