The highly velocitized escape of gaseous matter via the rectum whereby the rim of the sphincter is first inadvertently puckered inward, then violently blown outward causing a momentary flapping as the blast escapes then subsides.

The release of loud flatulence that sounds noticibly moist and wet. The hallmark of the Moist Flapper is that the flatula released always sounds wet but may not always actually be wet and result in the release of any feces aka Moose Jelly requiring a quick wipe.
Sherwin was rearranging his couch when he pushed on the heavy price and wound up straining and dropping a Moist Flapper. Fortunately it only sounded wet and didn't require a wipe.
