Hoi4 mod ideology

Some guy with a Hoi4 mod ideology was complaining that there isn't enough people interested in reading Carl Jung's theory on the archetype of Wotan.

HOI4ian 

An idea or statement revolving around worldbuilding, roleplay, alternate history, or other media that is so ridiculous or over-the-top that it would only work in Paradox's WW2 Grand Strategy Game "Hearts of Iron 4." Often used in the context of having a nation inexplicably win a war or become a dominant world power for the sake of aesthetics, political victory, or powergaming.

"Dude, Germany could have won WW2 if they just produced more Tigers!"
"Man, that's so HOI4ian."
