Finrot is a slight bacterial infection infection of the fins of a fish.
Often the symptoms are identical to a heavy over-production of male jelly.
To prevent unsustainable madness the victim should return to it's home planet where it will come to an orgy of invertibrate sex.

Prof.: Relax, my chum, there's no problem.You're just heavy with male jelly.
