Periscope 

When the end of an exceptionally long turd sticks straight up out of the water.

Similar to a "breach" (where the turd will arch up out of the water) but fully vertical.

Both of which, really really stink.

Dude, I just totally dropped a periscope in there.

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.

Peris

Orginally from Persian folklore. A Peris is

1. One of a race of beautiful supernatural beings

2. Any beautiful fairy-like creature

It is the used to describe a beautiful and graceful girl.

Soul Urge:

People with the name Peris have a deep inner desire for travel and adventure, and want to set their own pace in life without being governed by tradition.

Expression:

People with the name Peris tend to be orderly and dedicated to building their lives on a solid foundation of order and service. 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.

Sally: Hey Bob, I know you'd rather take Julia to the prom because you think she's prettier than me...

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

Bob: ( @Julia 😉)

Periscoping 

Periscoping is an advanced, but non-sexual form of spooning. Unlike being the big spoon or the inverse, little spoon/backpack/jetpack, both partners share equal responsibility. To periscope, one partner lines their dominant eye with the second partner's butthole, and 'peers through the scope.' At the same time, the second partner 'shades their eyes from the sun,' and shouts, "Land ho!"

She was really chill. We hooked up, spooned a bit, and then we tried periscoping it out. Anyway, that's how I got pink eye.
