Wicked Tuna

When engaging in heterosexual intercourse, the male participant will take a bluefin tuna and insert his penis in the fish. He will hump said fish until his penis is wet, slippery, and smells like a dead fish. Then he will rest the tuna down, and begin shaking his erect penis while the female participant scrambles to attach a string to his fishy dong. During this action, she will be screaming "We're gonna need a bigger boat!"
