Its a bit different from When I Bored, as that started from a non-pony fad (anime to TF2 to ponies)

Here this is ponys, to other media.

That said, I feel this can be sorted elsewhere. Perhaps we need a “MLPFIM Video Fads” to cover this, When I Bored parodies, the various Abridged Series, and so on, similar to the art fads one.
