Floodgate 

Having sex with a woman that squirts in a way that when you pull out, all of the fluid shoots out of her vagina at once.

"I was pounding away my girlfriend with her bent over her bed, right? Well she's a squirter, so when I pulled out it looked and sounded like someone fucking threw a bucket of water onto the floor between her legs. I've been calling her floodgate ever since."

"Holy tits"
