The 'You Like Krabby Patties' meme stems from the SpongeBob SquarePants episode 'Just One Bite,' which first aired in 2001. In the episode, Squidward tries a Krabby Patty for the first time and secretly falls in love with them while pretending to hate them. When SpongeBob catches him in the Krusty Krab vault surrounded by half-eaten burgers, he makes a hilariously smug face and says the iconic line. Since then, the image has been used across the internet to mock hypocrisy or to playfully confront someone about a hidden preference or secret they've been caught keeping.
