The Brainlet meme is a popular variation of the Wojak character, characterized by an intentionally deformed, shrunken, or absurdly shaped head to represent low intelligence or poor critical thinking skills. Emerging primarily from 4chan's /sci/ and /biz/ boards around 2016, it was originally used to mock users with subpar scientific knowledge or bad financial advice. Over time, the meme evolved into a massive collection of diverse illustrations, often featuring the character drooling or performing nonsensical tasks. It serves as the antithesis to the 'Big Brain' or 'Galaxy Brain' memes, acting as a visual shorthand for calling out 'low-IQ' arguments in internet discourse, gaming communities, and cryptocurrency forums.
