The sensation of having to take a shit which then passes, only to later return. Commonly occurs when the initial need to shit is stopped by an occupied bathroom causing you to wait. You both have to and do not have to shit.

Can also be used when referring to a suspicious fart that may be a shit in disguise. Since you will not be able to tell if it's a feet or shit until you let it free and in turn measure it's state.
Man that Mexican food did not sit well, I've been stuck with a Schrodinger's shit for like an hour now.

Get the Schrodinger's shit mug.
Someone who makes a shitty meme, song, or video and decides whether it was intentionally shit or not based on the response it got.
John: "No you see, the song is intentionally bad!"
Mike: "John, that's a schrodinger’s shit, you're full of shit."
