"Why does there gotta be so many psudo-scientific internet 'laws' of common human behavioral archetypes with a half baked Wikipedia entry?"

Because of SmokeyDope's law.

"If more than two humans ever exhibit the same behavior or particular complex that eventually there will be some armchair academic undergrad who will attempt to needlessly define it just to get to say "complex-fancy-sirname's law" "

Smokeydope’s law right there. Typical telltale signs.

Can I have SmokeyDopes Law where if more than two humans ever exhibit the same behavior or particular complex that eventually there will be some armchair academic undergrad who will attempt to needlessly define it just to get to say "complex-fancy-sirname's law"

No.

Tbf, Cunningham's law doesn't have a Wikipedia entry unto itself, just a subsection in the biography of the sort-of kind-of coiner of the aphorism. And it's not trying to be scientific or academic; the law is just a light-hearted joke that people are less likely to answer questions on the Internet than they are to correct statements.
