The 'You Locked The Door?!' meme originates from a high-energy scene in the 2003 film adaptation of Dr. Seuss's The Cat in the Hat, starring Mike Myers. In the scene, the Cat expresses sheer terror and disbelief upon realizing a door has been locked, trapping him in a chaotic situation. This over-the-top reaction became an internet sensation due to the Cat's exaggerated facial expressions and the relatable feeling of sudden entrapment. It is widely used to illustrate moments of panic, social blunders, or the realization of a self-inflicted predicament where there is no easy escape.
