Angry Birds, Rovio's 2009 mobile hit, built its comedy around the green pigs that squeal whenever a launched bird smashes into their fragile fortresses. The damage squeal became one of the game's most imitated noises, lifted into YouTube gameplay clips, Vine-era edits and meme soundboards where short cartoonish defeat cues rule. It still pops up in gaming montages alongside other iconic defeat sounds like the Fortnite death sound and the SpongeBob fail sting, because anyone who played the original recognises that half-second squeak as the universal signal of a pig getting bonked.
