I disagree that it's a joke, because they're absolutely nothing funny or clever or original about it, but you're right that the point is to jump on a bandwagon, and it's intentionally ironically disrespectful of everyone's time and attention, which is also the point. It's really just a spammy childish 4chan troll.

It makes strangers type seven paragraphs when someone uses it.

That one letter to seven paragraphs ratio is pretty funny when it happens.
