Rhymes With Grug is a creative evolution of the Grug meme, which features a primitive, low-intelligence caveman character often used to satirize modern complexity or express simple, primal urges. The 'Rhymes With' format specifically utilizes the character's name to generate variations of his persona, such as 'Shrug' for indifference, 'Chug' for drinking, or 'Drug' for altered states of consciousness. Appearing frequently on imageboards like 4chan and Reddit, the meme serves as a versatile template for absurdist humor, contrasting the simple life of a caveman with modern-day frustrations or niche internet subcultures through catchy, one-syllable wordplay.
