The phrase is German and translates roughly to asking since when the boogie could do that, which explains why it travels well as a reaction sound even outside German speaking edits. Online, the clip is shared in short meme formats where a surprising performance needs a verbal reaction, and its specific wording makes it recognisable after one listen. Because no widely confirmed original source is documented for the recording, its popularity rests on reuse in dance, party and fail edits rather than a single famous scene.
