The 'Guess Who's Back' meme originates from the 2002 music video for 'Without Me' by Marshall Mathers, professionally known as Eminem. Directed by Joseph Kahn, the video features Eminem in various satirical roles, signaling his highly anticipated return to the music scene. The specific clip captures the iconic opening hook where Eminem announces his presence with the lyrics 'Guess who's back, back again.' This moment has become the universal internet shorthand for any grand entrance or triumphant return. It is commonly used to represent situations where someone rejoins a group after a long absence, a forgotten trend makes a comeback, or an individual arrives to save the day in a dramatic fashion. Example captions include: 'Me returning to the group chat after a 5-month social burnout,' 'When the main character who supposedly died in season 1 shows up in the finale,' and 'The 3 AM motivation to change my entire life finally arriving.'
