GGMU stands for Glory Glory Man United, adapted from the melody of Glory Glory Hallelujah. Manchester United released Glory Glory Man United as a team song for the 1983 FA Cup Final, and supporters turned its chorus into a lasting terrace chant. Fans sing it at Old Trafford and away grounds, and the shorthand GGMU spread widely on scarves, banners and social media. Online, the recording is reused by supporters to mark wins, announce matchdays and rally other fans before big games.
