Rockerism is the belief that having a good time is more important than anything. People who believe in Rockerism (Rockerists) do not discuss religion or politics. This is done because they understand that these issues bring about endless arguing. It's about forgetting the things that separate you from the person sitting next to you. That's Rockerism.
