The exact recording behind this clip is unclear, which is typical for short meme audio passed around soundboards and Discord servers. The phrase itself comes from the long-running “erm, actually” nerd stereotype in internet humor, where a smug voice delivers an obvious or absurd conclusion as if it were science. It spread through TikTok edits, YouTube Shorts and meme compilations, usually captioned over characters doing fake math. It endures because the setup is endlessly reusable for any joke dressed up as logic.
