A Dry Dump is a fart that is so satisfying it will feel as though you've completely voided your bowels. Originally thought to be a "phantom poop," Dry Dump is most appropriately made/deployed while mingling away from lavatories. One should be sure to brag members of the opposite sex about such a fulfilling sensation.
While walking up the steps to my Bio class, I released such a great dry dump that I thought I had just left the bathroom.
