Missouri fountain

A Missouri fountain usually occurs when an elderly man inserts anal beads up inside of his asshole to leave for six days. A presumably younger woman would rip the anal beads out of the elderly man's asshole while in a fetal, ass up position causing the fountain of shit to copulate within the woman's vagina.

The regional association is related to Missouri being famous for toasted ravioli.

Yooo! That homeless guy in the alley just did a Missouri fountain with that hooker!
