What is the definition of Yearly Human Experiments?

"Yearly human experiments" is a phrase that humorously suggests that every year, researchers and scientists conduct bizarre and often unethical studies on humans, as if they were just trying to figure out how to make our lives a tad more... human. Picture it like this: "Every year, we conduct 'Yearly Human Experiments' where we test the limits of our subjects' sanity and willpower, like forcing them to dance alone in a room with a million disco balls for an entire year!"

Now, here's an unsettling example sentence: "The annual human experiments began this month when they decided to test our fear response by trapping us in a darkened room with a giant spider and demanding we scream 'carecrow' for the next hour, every single day."
