The 'Best Day Ever' meme originates from the upbeat song of the same name featured in the 2004 SpongeBob SquarePants Movie and later in its own dedicated episode in Season 4. The image depicts SpongeBob in a state of blissful optimism, singing with his eyes closed and arms wide. While the song was written to represent genuine happiness, the internet has primarily repurposed it for irony. It is often used to describe situations that are objectively stressful or disastrous, where the user adopts SpongeBob's unwavering positivity as a form of dark humor or coping mechanism.
