This clip comes from Angry Birds Epic, Rovio's turn-based role-playing spin on the slingshot series released in 2014. In that game the birds battle waves of green pigs, and the small minion pigs are the most common enemies, so their squeaky defeat noises are some of the most heard sounds in the whole game. Ripped and shared on soundboards, the little mourning wail caught on as a meme for mock-tragic fails, and it still pops up in game edits and funny compilations years later.
