The They Don't Know meme features a classic Wojak character standing alone in the corner at a party while others dance. Originally created in 2009 by artist T_Dabb, the comic illustrates feelings of social alienation and internal monologue. The meme gained massive popularity in 2020, with users adding captions starting with 'They don't know I'm...' to highlight obscure personal achievements, niche internet fame, or social anxiety. It serves as a relatable way to express the disconnect between one's internal world and a public social environment.
