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.

A compliment that also has a rude insult poorly disguised within it.

Upon hearing a 50/50 Compliment, you will not know whether to say "Thanks" or "Fuck you".
Christopher: "Wow, Laura, you're hair looks much better today than it usually does".

Laura: "Uhh, Thanks for the 50/50 compliment...Go fuck yourself".
