This clip is a stock recording of an electric tattoo machine, the kind listed as a tattoo gun effect in sound effect libraries. The buzz comes from the machine's vibrating needle bar, and the recording captures that raw, close-up hum without music or voices. Online, creators have picked it up as a quick way to sell a tattoo scene in short videos, memes and pranks, because listeners recognise the sound instantly even without seeing a needle. Its simple, realistic texture keeps it useful for edits that need an authentic studio atmosphere in just a few seconds.
