The 'REEEEEEE' meme, often accompanied by a distorted 'Angry Pepe' or 'Pepe the Frog' image, represents a high-pitched, frustrated screech used to signal intense annoyance or a breakdown in logic. Originating in the early 2010s on imageboards like 4chan, the term was initially associated with the unique alarm call a specific frog species makes when threatened, eventually evolving into a hyperbolic expression of online culture and social frustration. Today, it is used more broadly across social media platforms to satirize over-the-top reactions or to express genuine, wordless exasperation at annoying situations, broken game mechanics, or controversial internet opinions.
