flipper fart 

A high-pitched pulsating squeaker fart that encourages everyone in earshot to stand on their chairs and sing in unison: “they call him Flipper, Flipper, faster than lightning”

-Beware: dolphins swim in “pods” and where there is one others are sure to follow until the full fishing net is let loose in the sea (courtesy flushes encouraged)
-“Faster than lighting” often foreshadows the necessary speed of toilet access required to avoid aquarium cleaner be used on the innocent underoos and chair
-Causes those in earshot and smellshot to have an indescribable desire to meet Charlie the Tuna and smack that red beret off his fish head in retaliation
-some try to falsify a flipper fart by sitting on an acoustically tuned piece of sheet metal and letting room reverb produce an imposter flipper fart; kazoos pre-inserted into the anus are also not genuine flipper farts

Ronnie let out a flipper fart; let me grab the life jackets, swimming suits and take selfies to impress our friends on Instagram.

Fart flapper

The act of placing your nut sack over another's anus and letting your balls flap as they expel gas.
