spinal fart 

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.

Spinal Fartosis 

It is a medical condition when you fart and it travels to your brain through your spine and becomes a shitty thought or an idea.

Bro, your jokes suck and your ideas are ever shitty. I think you have spinal fartosis.
