The Grinch was created by Dr. Seuss in the 1957 book How the Grinch Stole Christmas, later popularised by the 1966 television special and feature films in 2000 and 2018. His grumpy voice and growling manner became shorthand for someone who dislikes Christmas cheer. Online, short growl clips in that style spread through soundboards and streaming alerts, where creators use them as a playful new follower notification. The association with a familiar holiday character keeps the sound recognisable even out of context, especially during December streams and edits.
