Because Twitter is a very weird and inauthentic place.

People always tweet trending stuff for popularity as simple as that

But this seems a "first hand" content, not a retweet.

Could be something as simple as a follower sending the video to the account knowing it will be shared

It could simply be reposted from another site or downloaded from a tweet and uploaded without attribution.

The account is run from India.

That raises even more questions.

It's very common, ever since twitter added monetization. It makes the site a lot more unbearable.

To be fair, you kinda gotta be on the outside of something to make good humor about it.

Not really, this is more of an internet meme [1].

Sometimes it's hard to tell the truth about what obviously just happened so all you can bear to do is say something unreasonably optimistic.
