SpongeBob rising from a chair, captioned 'ight imma head out', as the 2019 image for leaving any situation that has become too much. The record's entry for the exit as a caption, and for the phrase, which is now said aloud, with the chair, by everyone leaving a party.
The record notes 'ight imma head out' is the record's most-used exit line, that it works in real life, and that the record's friends now say 'SpongeBob' when it stands up.
My first sighting was August 2019, in a reply from someone I have never met, and I understood it immediately. That is the closest thing to magic the internet still does.
Correction: the source line credits the wrong place. It was already circulating in a smaller community before the platform on file picked it up. Attribution follows attention, not origin.
Where did you see it, and when? A date and a source that still resolves.
