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.

Period

A punctuation mark signifying the end of a sentence. Or, the time during a female's menstrual cycle when the unfertilized egg cell along with the freshly shed uterine lining is ejected from the uterus. It's not all blood as most people would think, and this process may take up to a week after the start of the period.

Try to end all of your sentences with a period!

Natasha's period is seemingly late. She's been stressed out dealing with school and all.

Honeymoon period

The period (usually two or three weeks) following the purchase of a new electronic gadget, when you are so much in love with your new gizmo that everything about it seems perfect. It doesnt matter how good or bad it actually is, the honeymoon period will always exist (believe it or not, even Vista users had a honeymoon period with their new OS). After the end of the honeymoon period, logic takes over emotion, and you can finally judge your new gadget more objectively, and thus decide whether the purchase was a success or failure. The duration of the honeymoon period is proposal to how good the gadget actually is.

Vista user: “This new Aero environment looks pretty slick, and look at those cool bundled multimedia tools!“

Same vista user, three weeks later: “Vista sucks! What‘s the point of having all those visual effects if the system is dog slow, and the bundled multimedia tools dont support any format that matters, like mp4 or divx avi“ (honeymoon period ended)

They value truth, justice, and discipline, and may be quick-tempered with those who do not. Their practical nature makes them good at managing and saving money, and at building things in the material world. Because of their focus on order and practicality, they may seem overly cautious and conservative at times.

Hi Peris, I'm Terrence. ;-)

perish the thought

A reassuring way of stating to an insecure friend that their comment (whilst maybe a bit true) was silly and/or foolish and the last thing on your mind.

Bob: Jeez Sally, Julia over you?! Lol, Perish the thought!

Bob: ( @Julia 😉)
