The sound combines two separate viral phenomena from different years. Angry Birds launched as a mobile game in 2009, and its main theme became instantly recognisable far beyond the game itself. The Harlem Shake began as a 2012 electronic track by Baauer, then exploded in early 2013 when short videos used its drop for sudden group dancing. Mashups pairing the game theme with that drop spread on meme soundboards and in fan edits, keeping both references alive long after the original dance trend faded from the mainstream.
