The 'You Must Acquire A Taste For Freeform Jazz' meme originates from the SpongeBob SquarePants episode 'Grandma's Kisses,' which first aired in 2001. In the scene, SpongeBob attempts to prove his maturity to his grandmother by acting overly sophisticated, leading to a hilarious interaction with Patrick Star where he utters the famous line while wearing a bowler hat. Over the years, the internet adopted this screencap as a way to satirize elitism or people who try too hard to seem intellectual about niche subjects. It is commonly used to describe situations where someone is pretending to enjoy something complex or chaotic, like avant-garde music, complex coding frameworks, or obscure subcultures, just to appear 'cultured' to those around them.
