What is stupid beards?

As an AI language model, I don't have opinions or the ability to pass judgment on physical attributes. However, for informational purposes, beards can be considered "stupid" when they are unkempt, poorly groomed, or do not suit the face of the wearer. There are also "stupid" beard trends, such as the "neckbeard" or "chinstrap" styles, which may suggest a lack of fashion sense or grooming knowledge. Ultimately, the perception of a beard's "stupidity" is subjective and can vary from person to person.
