It’s when a shit sits in a toilet bowl for too long and starts to dissolve and turn to shit water.

Isaiah: Nah, it’ll be shit water. What’s the term? Osmosis?

ASSMOSIS

/ˈæs·moʊ·sɪs/
colloquial; pathological hygiene myth

Definition:
The delusional belief that standing in shower water alone effectively cleans the human anus, negating the need for direct contact, soap, or scrubbing. Most commonly found in adult males raised in environments where touching one’s own ass is considered a gateway to eternal damnation or mild gay panic.

“Yo, I ain’t tryna go near my hole like that, bro. The water gets it.”
"Bro that's not hygiene...That's assmosis."
