Taco Tuesday is a long running weekly food tradition in the United States, where tacos are promoted and eaten on Tuesdays, and the phrase has become a ready made joke online. This short clip condenses that idea into a single shouted announcement that creators reuse across memes, short videos and soundboards. It spread through shareable food content and reaction edits rather than one single scene, and it remains popular because the reference is understood instantly, even when the video itself has nothing elaborate to set up.
