An even more hyperbolic variant of The 50-50-90 Rule. In a situation where a subject has a 50/50 percent chance of getting something right, they will get it wrong 100% of the time.
This "rule" was popularized within the Super
Mario Maker troll level community by
popular Twitch streamer CarlSagan42, and is just one example of a reoccurring joke designed to showcase how easy it is to
fool the average player into doing something wrong.
