Whole story for the totally unaware:
There's a cartoon called Rick and Morty that is working like a turbo autist magnet, not much different than MLP.
In one episode, one of the characters that the autists idolize, craves for this old Mulan promotional McDonald's sauce called Szechuan sauce.
Then, the autistic fans started to act autistic towards this sauce, because they want to feel like the idolized character, since he's supposedly really smart.
McDonald's sees this as a marketing opportunity and re-release the sauce, Rick and Morty fans get in line to get it, generating a huge demand. But since McDonald's only released this as a limited edition, only like 10 or 20 packs per store were available.
So, the people who actually got the sauce started to be greedy about it, selling it on ebay, or doing weird youtube videos about it for attention.
That's how we get to that webm. The guy who got the sauce started to charge $10 for one nugget dipped in sauce.
