American exotic tradition California folk hip show festival customs, men and women, old and young take off their pants and show their hips when they are on the train

There is a unique event in small towns in Southern California in the United States that attracts many men, women and children to participate every year. This "tradition" that makes people laugh is that people line up neatly next to the train tracks. When a train passes by, they take off their pants and show their butts to train passengers.

According to a report by the California News Network on July 17, 2012, this traditional event called "Moon Amtrak" is held every year in the town of Laguna Niguel in Southern California. Many people come here, men, women and children show their butts together to surprise train passengers looking at the scenery.

The event began in 1979 and began with a man betting with his friend that he would dare to show his buttocks to a passing train in exchange for his friend to buy him a drink. Subsequently, butt showing activities gradually became a trend and formed a festival attended by tens of thousands of people. Train passengers sometimes take off their pants and make a "friendly response" when people on the ground reveal their identities.

However, since nearly 10,000 people came to participate in the event in 2008, some urinated and defecated everywhere, and others exposed other parts of their bodies. As a result, the police cleared the venue and banned it, and the number of people exposed dropped sharply the following year. 2012 was the 33rd Hip Show Festival. The police banned people from parking their cars on nearby streets and sent police officers to patrol, reducing the number of people to less than 100. On July 15, 2012, only more than 70 people officially participated in the hip exposure activity.
