spinal adjustment 

when a man spreads a woman's legs, pins them back and fucks her so hard her back cracks. This custom became so popular in the early 1980's that some enthusiasts would have spinal adjustment parties and couples would simultaneously engage in this form of boning. The combined sound of all the cracking spines gave the aural illusion of crickets chirping. The practice didn't quite reach "fad" status, though, as it really didn't sound that close to crickets chirping and it was only interesting to the bystander for a few quick moments. Eventually, the party idea died out and currently spinal adjustments are practiced in the privacy of one's home. This has been known to save dozens of dollars in chiropractor bills, cutting health costs by 0.00001%, though statistics have only been kept since Valentines Day, 2012.

Harold: Hey, Fred, what's with Steph?

Fred: Fucked her so hard last night, I gave her a spinal adjustment.
Harold: Oh, okay. That's awesome. The way she was walking, I thought she had some kind of pussy rash.
Fred: No, it was great. Had her up to five pops. Got four more on the last thrust. Adjusted!!! (high fives)

spinal fluid 

Cerebrospinal fluid (Spinal Fluid) is a clear, colorless body fluid found in the brain and spinal cord. It is produced by specialised ependymal cells in the choroid plexuses of the ventricles of the brain, and absorbed in the arachnoid granulations.

The doctor extracted the spinal fluid using a lumbar puncture.

Spinal bleach 

A more advanced type of trick, where you dig your fingernails so intensely into your partners back, you rip their flesh in half revealing their spinal cord. Because of the intense pain, you must pour gallons of bleach to block it out. Afterwards, you cum enough into their lacerated flesh and fill the entire gap, proceed to seal the rupture with super glue. Whenever you need to re-fill the gap, stick a tube up their lovely anus and continuously cum up their spinal cord.

Guy 1: “hey man, have you recently done your partners’ spinal bleach?”

Guy 2: “hall yeah, tearing the back in half gets me to climax in like .2 seconds, crazy good.”
