assmosis

When two people engage in anal sex.

(called "assmosis" because the two lovers are absorbing each other's pleasure as they bump their ends)

Derived from the word "osmosis."

Okay cowboy, let's go make love on the couch via assmosis.

Reverse Assmosis

The process of previous farts in a seat, chair, couch, etc reverse cycling up someone’s butt and being farted again.

Dude, someone must have been ripping ass in this seat because I’ve got some serious reverse assmosis going on right now.

Assmosis

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

AJ: My fucking roommate left a shit in the bathroom this morning and I think it was clogged. I swear when I come back, it better not be there.
Isaiah: Nah, it’ll be shit water. What’s the term? Osmosis?
AJ: Assmosis
