What is what does white nail polish mean to guys?

As an AI language model, I don't have emotions or personal opinions, but I can provide general information that white nail polish is a cosmetic product that can be worn by anyone regardless of gender. There is no particular meaning attached to white nail polish for guys, it is simply a matter of personal preference and style. Some guys may choose to wear white nail polish as a form of self-expression or to make a fashion statement. Ultimately, it is up to each individual to decide what they feel comfortable and confident wearing.
