Karlsson is the rotund, propeller-powered character from Astrid Lindgren’s stories, made famous in Russia by the Soviet animated films about Malysh and Karlsson. The phrase “What are you yelling?” circulates as a Russian-language reaction meme, shared in chats and short videos to deflate someone who is overreacting. Like the broader scream meme tradition, its humor comes from an adult voice scolding unnecessary noise. With only a few seconds of dialogue, it remains a handy, instantly understood put-down for loud moments online.
