Angry Birds 2 is Rovio's 2015 sequel to the original Angry Birds mobile game, bringing back the flock for new slingshot levels and boss battles. Terence, the flock's largest bird, is known for his dark red feathers, spotted belly and unusually deep, gruff voice, which sets him apart from the higher-pitched birds around him. His grunts have become a handy shorthand online for something big, grumpy or unstoppable, and short clips of them circulate in gameplay videos, edits and reaction memes long after the game's launch.
