Terence is one of the original birds from Angry Birds, the mobile puzzle game launched by Rovio in 2009, where players launch birds at pigs. As the largest bird in the flock, he is known for his quiet, brooding presence and deep grunts rather than cheerful chirps. Short clips of his sounds began circulating on soundboards and in fan edits as Angry Birds grew into a global franchise with sequels, cartoons and films. The grunt endures because it instantly signals size, grumpiness and barely contained anger without needing any words.
