Meaning
A large dark gorilla, usually shown sitting or knuckle-walking, with broad shoulders and a heavy brow. It stands for the great ape itself and, by extension, raw strength and size.
Gym posts, heavy lifting, big protective friends and wildlife documentaries all fit, often with 💪 or 🏋️. It can also mean acting wild or loud. Example: “New personal best on the deadlift, feeling like a full gorilla today 🦍💪”.
