Can anybody explain this to me?

[marcipaans]

Because I am completely cofused and lost(YLYL-way).

That's a common schoolyard game. Two combatants hop on one foot like you see in the clip and try to knock the other to the ground or out of the ring formed by on-lookers.

In the context of a baseball players, I'd guess it's a less-violent way to resolve conflicts that Americans would resolve with fists.

They start hopping at one another long before the ring forms. And everyone is hopping, not just the pitcher and catcher.

Makes sense to me, but then again random-guy-on-internet isn't the best authority on things.

[marcipaans]

Even if it is true. I cannot belive people do not burst in laugh when they see it

[Oisterman]

This is why hockey is superior. Use fists.

[Xenonight2]

Yes, because Japanese are all asians, and Westerners couldn't possibly be weird for not getting it.
