to answer your question from earlier yes I speak English & I'm an American white guy.
Speak? Ok, sure. Write? Maybe not so much- better grammar & proper explanations would help a lot.
To translate: A 'Mario Calamity' seems to be a specific type of YouTube parody video, produced by multiple creators, that I assume shows Mario failing spectacularly during typical Mario game events. I can't be sure, as YouTube is currently going crazy & I can't actually watch anything.
