The 'I Bet He's Thinking About Other Women' meme features a four-panel comic-style illustration of a couple lying in bed. The woman looks suspiciously at the man, assuming he is unfaithful or dreaming of someone else, while the man is actually preoccupied with a completely unrelated, often absurd or overly technical thought. Originally drawn by illustrator Greg Cyr in 2016, the meme gained massive traction on Reddit and Twitter around 2017. It perfectly satirizes the disconnect between perceived relationship insecurities and the mundane, often bizarre internal monologues people have, making it a staple for relatable humor and niche subculture jokes.
