The 'Change Team' meme originates from the user interface of classic tactical shooters like Call of Duty, where players are given the option to switch factions mid-match. It evolved into a popular reaction image used to satirize people who quickly abandon their loyalties, political stances, or sports teams when things start going poorly. The humor stems from the blatant opportunism and lack of conviction represented by a simple menu selection. It is widely used across social media to mock 'bandwagon' fans or individuals who suddenly shift their opinions for personal gain or convenience.
