이 사운드에 대해
This is a short Polish voice clip, about two and a half seconds long, of a man bluntly saying 'zamknij już mordę' - shut your mouth already. The delivery is fed up and commanding, which makes it feel funny rather than genuinely hostile, like an exasperated friend finally cutting off a rant that has gone on too long.
