Grond, also known as the Hammer of the Underworld, is the massive, wolf-headed battering ram used by Sauron's army to breach the Great Gate of Minas Tirith in J.R.R. Tolkien's The Lord of the Rings: The Return of the King. In internet culture, specifically within the r/lotrmemes subreddit, Grond evolved from a terrifying siege engine into a viral sensation characterized by repetitive 'GROND' chants. The meme is typically used to represent an unstoppable force, a relentless obsession, or simply as a tool to hilariously derail comment threads. Its popularity stems from the rhythmic, cult-like dedication of fans who find humor in the orcs' singular focus on the battering ram's destructive power.
