They were occupied by Americans after WW2 (still are) and Americans are the ones who determine the popular image of people in the world (see coward Frenchmen etc). It also helps that Bavarians are historically very submissive, they are known to bow down to all foreign invaders without fighting back and sort of exemply the way other people would like Germans to be, that is some fat dude in Lederhosen drinking beer and being non-threatening and a bit dumb. As opposed to the evil Prussian militarist who eats children stereotype (these are the only two German stereotypes that managed to enter the popular imagination).
Bavaria
Austrians literally speak a Bavarian dialect and both Salzburg and Tirol were once part of Bavaria. (Salzburg for notably more time)
Everyone who buys Bavarian products shall be cursed and his children teeth and hands shall rot
My dad lived in Bavaria in the 70's, he said that they're more chilled out than the G*rms up north
>It also helps that Bavarians are historically very submissive,
They aren't submissive - they are stinky Catholics and therefore non German. If they are invaded by all kind of trash, it's like a liberation for them.
>they are stinky Catholics and therefore non German
Schlechtes meme.
Notice the Amrimutt/Vatican line.
Doesn't explain why Bawü is mostly unheard of

My next door neighbor is unironically from there.
