Put it at the end of a food or eating scene, just before the cut to everyone's faces, then follow it with a shocked reaction and a laugh that follows to sell the gag. It also works as the punchline after a boast about finishing a meal.
O tym dźwięku
This is a single, very short burp lasting less than half a second, with a blunt, guttural pop that cuts off almost as soon as it starts. It feels gross in a funny way, like catching someone mid-belch, and its suddenness makes it land as a quick shock gag rather than a drawn-out joke.
