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.
