In the world of Star Wars, one of the overarching points to the movies is balance. There is always an attempt to balance the force, whether it swings too much towards the Jedi or the Sith. With May the 4th being a pseudo-holiday and marketing stunt for Star Wars that focuses on promoting the heroes, the day after is colloquially known as Revenge of the 5th, being all about the Sith. It also happens that May 5th is also known as Cinco de Mayo, the day of remembrance of the Battle of Puebla to the Mexican people, which results in blended memes where Star Wars and Mexican culture collide.
