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.

reverse peristalsis

The term "reverse peristalsis" refers to the act of human fecal matter traveling up the esophagus due to a blockage in the colon sending fecal matter to the stomach. This is sometimes known as "potty mouth" and can be found on an episode of House, M.D.
