Open the Flood Gates

When two men who desperately need to urinate press the heads of their penis's together so that the tips touch each other and let the golden stream flow into the other's shaft-hole.

A variation of this is when neither party involved has been circumcised, and both foreskins are stretched out to be pressed together. This may be referred to as "Bursting The Flood Gates"

Chris: "Hey man, you bustin'?"
Heath: "Totally!"
Chris: "Wanna go Open the Flood Gates?"

Bruce: "Hey Abraham, wanna go Burst the Flood Gates with me?"
Abraham (shakes head): "Sorry Bruce, I'm Jewsish."

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"

floodgate fart 

The fart you have right before you take a shit. Usually when you're popping a squat this occurs or when you're situated on the toilet

I was having a hard time in the loom, until that floodgate fart came, then it was smooth sailing.
