The 🦾 mechanical arm emoji is often used to signal strength, power, or capability. From a romantic partner, it could imply they see you as strong and capable, or that they find your technical skills or intelligence attractive. Between friends, it's a playful way to flex your "robotic" abilities, like being great at video games or coding. Used by itself, it's a subtle flex, but paired with other emojis like 💪 or 🤖, it's a clear statement of your technical prowess or physical strength. Overall, the mechanical arm emoji conveys a sense of capability and control.
