Grug, also known as Caveman Wojak, is a variation of the classic Wojak character depicted as a primitive neanderthal. First appearing on 4chan's /pol/ and /lit/ boards around 2017, Grug serves as a satirical personification of anti-intellectualism and traditionalist 'low-IQ' perspectives. The character typically communicates in broken English, often referred to as 'Grug-speak,' focusing on simple concepts like hunting, gathering, and hitting things with clubs. It is frequently used to mock overly complex modern problems by proposing primitive solutions or to ironically celebrate a simpler way of life. The meme has since evolved into a versatile template for commenting on technology, society, and tribalism through a prehistoric lens.
