What does it mean to hang a pair of dice on an American car? Often seen in movies and cartoons.

Hanging a pair of dice on an American car usually represents luck. This custom originated during World War II, when the US Air Force faced an unfavorable situation. Some pilots use dice to predict whether they can return smoothly before performing a mission. If you roll two dice with a lot of points, hang them on the dashboard and hope they will bring good luck. This practice became popular later, and pilots followed suit, hanging dice on the rearview mirror as a symbol of luck.

In the Elvis Presley era, retro style and automobile culture rose, and this custom became popular again. Dices are also made and sold in the form of plush dice toys, which become a symbol of good luck or show a cynical gambler temperament. Similarly, there are two multi-faceted or black eight billiards, Rubik's cube, digital baby ball and hanging eggs. This custom often appears in movies and comics, and has become a popular pattern, even in baseball caps and other clothing.
