The clip comes from a German short-form video built around duckweed, with the on-screen message explaining that the plant is edible and non-toxic and the creator expressing a fondness for it. That odd pairing of a straightforward plant fact and enthusiastic approval helped it travel as a small meme sound, especially among viewers who enjoy deadpan food humour and nature clips. It survives because the joke needs no translation beyond the hum itself, so editors can reuse it whenever a plain ingredient or foraged plant is treated like a delicacy.
