A 4 year old once told me, on his passing wind
“I fluffed”.
Sorry, I was busy launching a sea pickle.
When I first saw the lists in the OP, I thought ‘solids’ was one of the euphemisms. I kinda like it: “I gotta go drop a solid,” or “I gotta go lays some solids.”
Other poop terms off the top of my head:
Deuce, as in, “Where’s Bob?” "He’s deucin’ "
Dr. Rhea, as in, “Dr. Rhea came over last night, and she was quite angry.”
Gasses:
Musty gust
Toot
Rotten ham, as in, “Alright, who’s got the rotten ham?”
One-part harmony
Happy
Ah yes. Poop and farts. A subject common to all (and well worth a few giggles).
Pinching one off
Making meatloaf
Releasing trout
Making mookie
Meditating
On the gaseous side of things:
cracking one off
stepping on a duck
fluttering one’s anus
speaking the unspeakable
clearing the other throat
Unleashing the kraken
Dropping a bomb
Releasing the hostages
The brown army storming the porcelain beach at Normandy
