A potato that is also a fish. Commonly worshipped by middle schoolers, the fish potato is believed to be the soul essence of everything around us. It can be used in any sentence and still kinda make sense.

No one knows where or how it started, but we do know it's everywhere now. You can't escape the fish potato.
Middle Schooler: Darn. I haven't been feeling very fish potato lately.
Other Middle Schooler: Oh my fish potato! That's awful!
