San Francisco Fire Hydrant 

When one man lays on his back with his erect penis pointing upwards, his partner then places his penis in a perpendicular fashion against the first mans. This arrangement simulates the appearance of a fire hydrant and connected hose.

New Jersey Fire Hydrant 

When your girl is being crowded by a bunch of dudes at a party, and you proceed to pee on her, marking your territory, ensuring no one tries to talk to her again due to the piss aroma that presides on her lower body. (Exception to upper body if you have a strong stream)

Mike: “dude what’s that smell, did someone pee in here?”
Devon: “Jake just Gave Hailey a New Jersey fire hydrant.”
Mike: “haha what?”
Devon: “Yeah dude just pissed on her in front of everyone to ensure his territory.”

Mike: “haha sick”

Albany Fire Hydrant

This act requires two people: the hydrant (uncircumcised) and the hose. The hydrant wraps his foreskin around the hose's puckered lips (preferably named Tyler) and pisses into his mouth. The hydrant preferably has to shit, and after doing so, the hose uses the piss reservoir to clean the hydrant's asshole (i.e. bidet).

Marlon: Dude, I just ate a shit ton of Taco Bell, my asshole is probably gonna be covered in shit later
Tyler: Don't worry dawg, I can run an Albany Fire Hydrant on you
