Fish Tank(ing) 

When a female has a smelly pussy, and traps you under the bed sheets.. much like the common Dutch Oven.

The hilarity of my boyfriend's dutch oven was quickly dissolved when I instead spread my legs and the dreadful smell of pussy entraped him in a tank of my vaginal fishyness. Boom, fish tank(ing).

When you take a piss in a girl's mouth and while she gargles you jerk off in her mouth.

Dude: Hey baby, I heard about this new thing called the "mississippi fish tank", wanna try it?

Babe: Sounds weird? What is it?

Dude: You trust me?

Babe: Mmmm...yeah?

Dude: Open wide then, close your eyes, and try not too swallow.

Fish tank time 

The period of time where sex (usually heterosexual penetration) is so boring that you'd rather pay attention to the guy's conveniently positioned fish tank than actively engage in sex.

A: "Hey, I heard you and Tom hooked up last night, how'd it go? Is he worth a go?"

B: "For someone who's so experienced, there was way too much fish tank time. Would not recommend."

Fish tank 

A box made of glass, often containing 1 gallon of water, with 10 goldfish that did in a day due to ammonia poisoning.

“What’s wrong with my fish tank? Everything’s dying!“
“You put things that poop in it.”
