Muddy Fishtank

The act of anal intercourse until ejaculation. But before removing the penis from the anus, the inserted male will urinate into the anus.

I thought he was really nasty until he gave her a muddy fishtank.

fishtaco

An especially delicious, fishy lip dish served with a side of kinky fries and Bailey's. Once you've had fishtaco, you never goin back

Dave: Ugh man, this day was a total bummer.
Rocky: Perk up man, I heard you're having fishtacos for dinner!

Rammstein: In America, they serve fishtacos for breakfast AND dinner.

big fishy

this is when you take both your hands and stick it in someones buttcrack. it should look like a simulation of the little fishy, but with more work and effort to piss the person off.

oh no not the big fishy!!! =O

Little Fishy

this is when you take your hand, and in a wavy motion, stick it in there butt crack. it should look like a fish swimming into there buttcrack. it doesnt have to be directly inside, thats just gross. but over there underwear is fine.

-most guys absolutely hate this!
so have fun torturing them with this technique =

i gave my friend a little fishy one time and he had a freakin heart attack. then got really angry with me and tried to do it back. it can be fun =
