When you roughly shove two of your fingers into the anus of another individual, its a game of who can scream the loudest.

Refers to where you are unknowingly expelling a "separated pair" of stumpy poop-logs (rather than just a "standard" one-piece turd of considerable length) with a sizable "gap" of pressurized methane in between them; the result is an explosive whooshy bang partway though the dump that echoes hollowly in the toilet-bowl and is amplified/intensified by said bowl, just like the sounding-board of a drum or stringed instrument.
A backfire-poop can be highly embarrassing for the pooper if others are within earshot at the time. Some guys, however, are actually proud of making these "impressive" anal indiscretions, since it proves that they only produce "manly-sized" turds which "seal in the combustion", with no blow-by from a minuscule-diameter poop-log's allowing the gas to wastefully/splutteringly seep past the emerging turd in a much-less-spectacular noise-display.

It's where the guy sticks his hand in the woman's ass and grabs some poop and then rubs it on his dick and shoves it back in the girls ass or pussy

When your dog poops a big pile of crap in part of the yard and all of a sudden a storm kicks up and spreads pieces all over the lawn.. Tumble poop.
