Maybe you should find the real name and post it as a reply.

It’s part of a cheeky joke. There’s an adage that if you really need to find a correct answer, go online and confidently give the wrong answer. More people will jump on to tell you you’re wrong than would answer the question if you asked.

That’s called Cunningham’s law. The joke (which is actually quite funny) is that GP gave the wrong name for it and proved it.

It wasn’t clear and I understand the confusion but welcome into the joke, my friend. :)

Or maybe Cole's Law

I always knew it as oddsockmachine's law.
