50/50 friend 

A 50/50 friend is a person you talk, or hang out with a lot, but you don't have a very strong connection with them, or they have friends they like more.

Me and Andrew are 50/50 friends. We talk a lot, and we meet up after school, but he likes his friend Max more.

I'm Jessica's 50/50 friend. She has other friends she likes, but we walk together, talk together, and hang out at the mall.

Me: 50/50 friend means you are friendly with someone, but you have other friends you like more.

50/50 Day 

A 50/50 Day is when you’re having a day that isn’t great, but also isn’t terrible. Some good and bad came out of the same day.

Person 1: Hey, how has your day been?
Person 2: Eh, I’ve had a 50/50 Day.
Person 1: Why’s that?
Person 2: I got a promotion at work, but when I left for the day I noticed someone had scratched the whole front end of my car while backing into their parking space.

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.
