Giga Chad began online in 2017 as an exaggerated evolution of the Chad character in meme culture, linked to photos by photographer Krista Sudmalis that spread across Reddit and image boards. The character came to represent an impossibly confident and muscular ideal, usually played for irony rather than admiration. As short form video grew, creators attached dramatic sounds to Giga Chad edits, entrances and transformations, and the clip became a reusable reaction for success. Its popularity continues because the joke is instant and works without any context.
