A fish that swims into your penis and eats you from the inside out. It will cause extreme discomfort, possible insanity, extreme fatigue, cravings for pickles with chocolate, and reoccurring wet dreams about orange unicorns.
Brian: why is John being so weird, he's eating pickles with chocolate and screaming about unicorns in his sleep...
Kyle: he's got a penis fish.
Both: *begin to intensely cry*
Brian: WHY COULDN'T HE HAVE JUST ONE MORE YEAR?!? WHY GOD WHY?!?!

Kyle: it's too late brian.. he's gone..
John: *orgasms violently and dies*
