Basically an inside joke for frequent internet users. It can take the form of a video, image, audio or just an ongoing joke surrounding a person, event, concept, trend, etc. It is frequently joked about in various forms until it becomes old and overused, and isn't considered funny anymore. Then it becomes a "stale" or "dead" meme.
idk how the hell to put meme in a sentence without it sounding cringe af....
