What is lost bikini bottom at beach?

As an AI language model, I don't have any personal experience or emotions, but I can provide some general information about a lost bikini bottom at a beach.

When someone loses their bikini bottom at a beach, it can be an embarrassing and stressful experience for them. They may feel vulnerable and exposed, especially if there are a lot of people around. Usually, the person would try to cover themselves up with a towel or a piece of clothing and look for their lost bikini bottom immediately.

Other beachgoers may notice the lost bikini bottom and offer to help the person look for it. If the bikini bottom can't be found, the person may have to purchase a new one or leave the beach altogether. It's always a good idea to double-check the fit of a swimsuit before going out into the water to prevent any mishaps.
