The 55 Gallon Fish Tank

When you muff dive into a woman that is made of at least 55% body fat and come back out for air smelling like Nemo's abusive alcoholic uncle.

Hey Steve, you douchebag, after I took her out to a nice dinner at Popeye's we went back to her trailer where I gave her The 55 Gallon Fish Tank. Four showers later and I still can't wash her mush off my moustache. Overall, it was a great date with your sister. Asshole.

Fish-Tank Wank

When a man gets sexually aroused and 'horny' so he masturbates and when he cums he lets his seaman fly into the fish tank, killing the fish, but resolving his sexual fustration.

I had a wank last night and didn't want a huge mess all over the carpet so I did it in the fish tank!

Shit, i appear to have killed my fish.

Fish-Tank Wank's are the best!

Fish Tank

When someone who is skateboarding or running does not notice a pane of glass and collides with it.

“How‘d you break your nose?”

“I didn‘t see the glass door when I ran inside and I totally pulled a Fish Tank."

To pop a fish tank is to basically to finger a girl in her vagina really hard.

"Dude, you pop a fish tank. NO WAY!"

"Nice!"

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).
