an enjoyable fart that vibrates so hard and loudly it decompresses your spine and cracks your lower back. you may feel so embarrassed or proud depending on the audience but won't matter because you feel double relief.
My chiropractor suggested that I eat a burrito wrapped with navy beans, hard cheddar, sour cream cheese, potato chunks, and grade D beef to give me spinal farts because he's tired of cracking my back for cheap pay.

England's loudest band. The main members are David St. Hubbins (Guitar and lead vocals), Nigel Tufnel (Lead Guitar), and Derek Smalls (Bass). Rumour has it these guys are actually the American actors/filmakers Michael McKean, Christopher Guest and Harry Shearer (who also plays many characters on The Simpsons) respectively. Best known for their 1984 rockumentary "This Is Spinal Tap", directed by Marty Di Bergi (who, rumour has it, is really the well known film maker Rob Reiner!).

Filmed an entertaining sequel in 1992 called "The Return of Spinal Tap" which mostly featured live footage of them playing a gig at the Royal Albert Hall in 1992, plus some interviews.

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)

BLOODY GREAT 'rockumentory' called 'This is Spinal Tap - basically its about a fictional English Heavy Metal band called Spinal Tap (no!!!) who include Nigel Tufnel (guitar) Derek Smalls (bass)and David St. Hubbins (guitar) and a range of 15 drummers who all died. One in and 'unfortunate gardening accident' and another 'spontanoeusly combusted' on stage leaving nothing but a green blob on his seat, on their 'Smell the Glove' tour. Bit of Sex Pistols, and a bit of every 80's hair metal bands EVER. I would be here 4eva talking about it so GO RENT/BUY IT AND WATCH IT!!!!!!

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.
