"Moshing and broken glass just don't go together"

This quote by Billie Joe Armstrong is a reminder to be conscious of our actions and to be knowledgeable about our environments. It is a cautioning to be careful when moshing, a kind of dancing that includes pressing and shoving, as it can be hazardous and cause broken glass. Armstrong is suggesting that moshing and broken glass do not mix, as broken glass can cause major injury. He is reminding us to be familiar with our environment and to be careful when moshing. He is also suggesting that we should be mindful of our actions and understand the potential effects of our actions. By bearing in mind our environment and our actions, we can make sure that we are safe which we are not putting ourselves or others in risk.
