butt geyser

The act of filling up ones anus with a fluid, typically water from a hose. Then releasing the water like a geyser upon an unsuspecting victims head.

I stuffed cheese curds into my ass hole and then with a medically issued super soaker and careful precision I received an injection of One love Kombucha into my anus. Then during an ugly sweater party, many months later, I pulled down my pants spread my butt cheeks and with the the force of old faithful I shot my cheese curd laced kombucha turd Butt Geyser all over the head of one special party goer ronnathan blox.
