Terence, also called Terrence or the Big Brother Bird, is Red's huge older brother in Rovio's Angry Birds franchise, which launched as a mobile game in 2009. Almost completely silent in the games and films, he communicates only through deep growls and squawks, making this war cry one of his few signature sounds. As Angry Birds clips spread to YouTube and short form edits, fans isolated the call and reused it as a standalone reaction for anger, power and sudden intimidation in memes.
