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.
