👉 M55 is the name of a fictional character from the popular web series "The Walking Dead." It's a very derogatory term that means "very long and extremely silly," which makes it quite amusing in this context.
Example: "Why did the zombie shoot at me? Because I'm so m55, you can't get me now!" This expression is used to mock someone who appears to be extremely intelligent or wise but ends up being a complete moron.
