The phrase 'doe is normaal man' is Dutch slang for telling someone to behave normally, and the clip circulates as a reaction sound on meme pages and short-form video. Like many one-line meme sounds, it spread because the wording is instantly reusable: anyone filming odd behavior can caption it as not normal. Dutch-speaking creators use it most, but the blunt tone translates even for viewers who only catch the vibe. It sits comfortably next to other deadpan reaction clips that call out strange behavior in a single line.
