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."
another word for a whore, or a person who has been with a lot of people; it originated while playing the sexual chain game, where you try to see how many people you are linked to sexually by knowing who the people you have been with have been with and so on. a person is a floodgate if they have been with so many people that you actually have a lot of choices between who you can choose for the next link in the chain.
