Refractin' 

The period of apathy after a male ejaculates due to the massive release of dopamine neurotransmitters into the brain. Comes from the psychological term "refractory period."

"Yo dawg, how was the girl last night?"
"Really good, I'm totally refractin' right now."
"Sick man! You did her?"
"Nah dude, I kicked her out of my house and then masturbated furiously."
"Oh... that's odd."

Please to refrain 

Tabrizi proverb (made famous by Qalandar of Tabriz)

To cease, desist, stop whatever it is you're saying or doing. A badass thing to say to someone when you want to lay the smackdown on them.

Maajid Nawaz, please to refrain. You being defecations.

addition by retraction 

The idea that you earn some major points as a medical student if you do an exceptional job and remain utterly enthusiastic while performing a seemingly mundane task such as pulling back tissue in surgery for your attending doctor.

Student 1: "I can't believe Johnny got that residency spot. Must've been his positivie attitude and his efforts to do everything he could to help out his attendings in surgery."

Student 2: "Yeah, must've been a case of 'addition by retraction'."

Bop-type Refrain 

An extremely esoteric nickname for cocaine. In the original lyrics to the Cole Porter classic showtune "I Get a Kick Out of You", the second verse begins is "Some get a kick from cocaine". As the years passed, that was changed to "Some like the bop-type refrain" so kids could continue to put on "Anything Goes" as a high-school musical.

People aware of this, wanting to demonstrate their cultural refinement and speak about cocaine, all while avoiding eavesdroppers and self-incrimination, replace the technical name of their drug of choice with "Bop-type Refrain" (or simply "Bop-type", though the later option brings with it a tremendous risk of losing your audience.)

Chris: I'm sick of referring to cocaine as "yatch". It's gone too mainstream.
Kevin: How about "Bop-type Refrain"?
Chris: What the - oh, I get it. I didn't know you were a devotee of musical theater.
Kevin: Eh, I know the Sinatra version.

Refrain

To stop. Often followed by 'from'. 'Refrain' is usually used when speaking about human action.

"Please refrain from using your cell phone in the restaurant, ma'am."

Normally he would have made a Tom Arnold joke at a moment like that, but he was able to refrain from doing so.

Age refraction threshhold

the 2 year anomaly in the space time continuum in which asain females go from lookin really young to suddenly lookin 800 years old.

Ming is a victim of the age refraction threshhold.
