lol its actually a traditional game. try searching 말뚝박기

many other countries also have something similar

In Russia it was called Slon (the elephant) - team one jumps on team two, then team two tries to walk. And there’s a “stationary” version by the wall or a tree.
I have only heard of it being played in Soviet times (pic 1), but apparently this is still happening in summer camps and such (pic 2)

…Oh…

Well, it’s certainly eye-catching.

This game is called cavall fort (strong horse) in my language.

Is that the game from fat Albert?

Does the standing kid lift all the others up in a massive stacked Tombstone(the wrestling move)?

Stumble away! Stumble away!!

Centisuck?
