The "Batman Signal" meme originates from the iconic distress signal used to summon the DC Comics superhero, Batman. This image, typically depicting the Bat-Signal projected into the night sky, symbolizes an urgent call for help or the need for a specific individual or skill to address a crisis. In meme culture, it's frequently used humorously to indicate that a particular person, object, or concept is required to solve a problem, often with an exaggerated or ironic tone. For example, people might caption it with scenarios like "When there's free pizza, the 'pizza signal' goes up for me" or "The 'tech support signal' when my family needs computer help." It highlights a person's specific role or expertise in a given situation.
