Plankton, full name Sheldon J. Plankton, is the tiny green villain from SpongeBob SquarePants, the Nickelodeon cartoon that premiered in 1999 and is voiced by Mr. Lawrence. Obsessed with stealing the Krabby Patty formula, he fails in almost every episode, which made his frustrated screams a natural meme source. Clips of his aughhh yell were cut from episodes, shared on soundboards and social media, and reused as a shorthand reaction for rage, defeat and dramatic overreaction, keeping the sound popular long after the original scenes aired.
