When a lactating nipple projects milk in three or more directions at once. Usually a result of careless nipple piercing. Handy for mothers with triplets.

Trevi Fountain 

When two lovers, a man and woman, urinate in the same toilet.
A women peeing sitting down and the man pees between her legs at the same time.

“We both had to piss so bad at the same time, so we decided to go Trevi Fountain and get back to bed.”
