And now they are making us even more jealous by doing human pyramids together while on a yacht in paradise somewhere.
It's called a human pyramid because it looks similar to a pyramid...
...but instead of bricks, it's made with humans.
Human pyramids are associated a lot with cheerleaders. Sometimes they include only three people, other times there can be many more people.
For example: In this picture, there are six people participating, and each is in their underwear.
The science behind the pyramid is fairly simple: You put some people on the bottom, then with each "layer" you put less and less people. Until there is one person at the top and a bunch of people in pain underneath them.
In my personal opinion, these people kind of fucked up because this isn't so much a pyramid as it is a square with a hat.
So, anyway, now you know about human pyramids. Have fun, bye!
