Angry Birds was released in 2009 by Finnish developer Rovio Entertainment and became one of the first huge mobile gaming hits, built around slingshotting birds at green pigs. At the end of each level the game rates your performance with one to three stars, and this first star sound marks the basic clear. As gameplay clips, parodies and edits spread across YouTube and later short form platforms, the short reward chimes were lifted for memes and edits. Its star sting survives because everyone recognises the rating joke instantly, even outside the game.
