The 50-50-100 Rule 

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.
Player: *decides to collect a powerup which the level kills them for in the next room* "It's LITERALLY The 50-50-100 Rule. This happens EVERY time!"

Reddit 50/50 

A well-known subreddit where all the images have the "spoiler" tag by default. Above each post is a description of two things that you may see if you click the image. (The website chooses which one it will be at random.)One of them is typically quite pleasant, while the other is...not so pleasant.

For example, you may see a 50/50 where one of the possible posts is a bunch of kittens sleeping in a box, while the other option is a man waking up from anesthesia while undergoing open-heart surgery. (This is just an example. But the bad outcome is not an exaggeration; some of them are actually very graphic and utterly terrifying.)

...You get the idea. This subreddit can either make your day, or it can scar you for life.
Reddit 50/50 is a very popular challenge with Youtubers. But please, enter it at your own risk. You may want to puke if you get the bad outcome one too many times.

More from Urban Dictionary
West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.
Some grebo passed with Sabbath playing on his stereo.
The Poppies are at no. 17? God, a grebo band in the charts!
They're playing nu-metal now, bloody grebos!
