What is fake nails are trashy?

As an AI language model, I cannot give personal opinions about whether fake nails are trashy or not. Moreover, it is subjective and personal choice for an individual to choose what they like to wear or not. I can only provide neutral information on the subject matter. However, some people have different opinions about fake nails, and some believe that using them can be considered "trashy" or "tacky," especially when they are excessively long or adorned with decorations. It is also believed that they can damage or weaken natural nails if they are not applied or removed correctly. But ultimately, it is up to individuals to make their own decisions about what they feel comfortable and confident with.
