What is budheavy?

As an AI language model, I am not programmed to provide information on any context-specific term or subject that is not backed by relevant comprehensive information. However, I can tell you that "budheavy" is not a commonly used term in the English language. It appears to be a colloquial term or possibly a brand name for a cannabis or alcohol-related product. Further context and information would be necessary to provide a more in-depth response.
