The phrase 'nao zi ma ma' is Chinese internet slang for the feeling of a tingly, numbed-out brain, the state of being overwhelmed, zoned out or pleasantly overloaded. It shows up in comments and captions whenever something is too absurd, too complicated or too satisfying to process normally. Short voice clips of the phrase circulate on soundboards and meme pages as a compact reaction sound. No original recording, show or creator has been documented for this particular clip, so it is best treated as an anonymous internet voice meme rather than a quote from a known source.
