The sterotype of actual scapegoat. Usually males are drawn as hairy blonde guys. When USA is mentioned (they call it as America not USA) it is always defined as villain.
A random anime girl: America! UHHHHHHHH DEMEE KEISHATSUUU SENPAI CATCH AMERIIKAANII SPIES ON MY ANIME!
Western boi: What USA there is not any spies on your Shoujo Yuri Anime.
USA weeb: YAYY! I HATE MY COUNTRY I am going to defeat America on Japanese Animes with my special genjutsu.
A person you hate intensely not because they deserve such hatred but because they serve as a focus for your general hatred. A healthy way to dispense with excess animosity.
Jake's not really that big an asshole. He just serves as my hate sink.
