The Green Man meme stems from the cult-classic sitcom 'It's Always Sunny in Philadelphia,' specifically the persona adopted by Charlie Kelly. Wearing a skin-tight green spandex suit, Charlie becomes 'Green Man' to serve as a mascot or a source of pure, unadulterated chaos during sporting events and bar shenanigans. Since its debut, the character has become an internet symbol for wild enthusiasm, social awkwardness, and 'unhinged' behavior. Users typically apply this template to situations where they feel hyperactive, weird, or ready to cause a scene in the most hilarious way possible. It remains a staple for fans of the show and lovers of surreal physical comedy.
