If something is the coolest of the cool, the biggest of the big, then it is "Whale Penis," because penises are important, and nobody rocks the penis harder than the whale, owner of the world's largest penis.
Sin City is so Whale Penis, man, that the day I saw it, my wife and kids left me, I got fired from my job, and my car blew up, but it was still an awesome day because I saw that Whale Penis movie.
