The 'Wrong Side of the River' meme originates from the 1999 adventure classic The Mummy, during a high-stakes escape from the City of the Dead, Hamunaptra. As Rick O'Connell and his team flee across the water, the treacherous Beni Gabor mocks them from the safety of the opposite bank, shouting that he has all the horses. Rick retorts with the iconic line, 'Looks to me like you're on the wrong side of the river,' just as the Mummy's curse begins to stir. The scene became a viral sensation decades later, used to represent situations where someone is prematurely celebrating a victory while being oblivious to their own imminent failure or unfavorable position.
