A chaotic brainrot anthem that blew up in late 2025 after TikTok got its hands on it. Originally posted by some legend called cassidywahhahh2, the clip turned into a full-on meme because everyone kept singing the stupid lyrics like it was the national anthem. Features iconic lines such as: “What is this diddyblud doing on the calculator, is blud Einstein? What is this diddyblud doing on the calculator, is blud Estein?” The lyrics mean absolutely nothing, relying on peak 2024 slang like “blud” and “diddy” to refer to literally anyone acting goofy. Used when someone is acting strangely serious or “mysteriously smart” over something simple, usually involving a phone or calculator.
