Bad Piggies is a physics puzzle game from Rovio, the studio behind Angry Birds, in which the pig Ross builds rickety vehicles from spare parts and tries to reach a goal. Falls are a constant part of that loop, because most builds wobble, break or tip over before they succeed. Short clips of those moments have circulated on soundboards and in gameplay videos as quick reaction sounds, and this falling variant is used in the same way, as a compact audio shorthand for a build collapsing.
