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.
