South Park is an "adult" animated cartoon created by Trey Parker and Matt Stone, two libertarians who have a "everything is dumb and caring about things is stupid" approach to politics and life in general. South Park often met controversy for its crude humour, and as a result, was very popular with teenage boys who uncritically adopted the smug nihilist attitudes of its creators. You could think of it kind of like the proto-Rick and Morty if that helps.

They did episodes with extremely racist characteristic sterotypes of a Chinese resturant owner and Japanese owner fueding with each other in like a turf war. Their pronunciation of their "City" themed dishes sounded like "Shitty" like Shitty Kung Pow. Shitty chicken. It was also mirroring the Japanese and Chinese fueding historically. One would think they'd be allies being practical neighbors but alas.. and in one episode they did a differences between Chinese and Japanese mocking how Amerikkkans think all Asians are the same.

I won't link them but you can find the relevant clips on YT.
