A psychological effect in which the victim is manipulated into thinking that the fake flag is the real and therefore the correct flag of a certain country. The name comes from the infamous Wikipedia edit war where users have deliberately put the civil-ensign flag of Austria-Hungary as the national flag even though Austria-Hungary didn't have the national flag.
I'm so sorry to hear that you have the Austria-Hungary Effect.
He thinks that the flag with a Kangaroo is the real flag of Australia, He probably has the Austria-Hungary Effect.
My students have recently complained about the flag I drew and said that it was not real. After some research, I discovered that this flag was never used and was made by some fan on r/vexillology. I have experienced the Austria-Hungary Effect.
Sir, given that the flag you saw was not real and you have been manipulated for years, you are diagnosed with the Austria-Hungary Effect.
Also known as "Yangster", "Yangie Commie", or even "Yangist Communist", a Yang Commie is an Internet user who is a self-proclaimed Marxist-Leninist (Authoritarian Communist) and a notorious simp for the character Yang Xiao Long from the American-produced anime series RWBY. They emerged on Yang Xiao Long's birthday celebrated on July 28th, 2023 on Twitter (known also as X) and are also present in Mastodon.
They are often spotted with profile pictures of Yang Xiao Long with communist imagery. Their goal is to make Yang Xiao Long be in a relationship with a boy after having witnessed Yang kiss Blake in Volume 9 of the series. They often make satirical and trollsome statements such as Volume 69 (a satirical chapter where Yang Xiao Long would most likely end up being married to a young man of her age) or shipping them with their own male OCs but they also provide some truthful information such as Yang not being in a romantic relationship during Volume 1.
Yang Commies tend to be often anti-LGBTQ+ due to their views on RWBY and Yang Xiao Long.
"Dude! This guy is spewing shit on the Internet about Yang being attracted to the opposite sex. He's probably a Yang Commie."
"I've never seen crazier homophobes than the Yang Commies who think that Yang Xiao Long from RWBY should have kissed a boy instead of Blake."
"I guess you can say that they are a 'Yang Commie'."
