Third question is who is invited. I will translate to explain my definition of a thug or a gangsta. Gangstas make they own rules, or follow rules they vocally agree to follow. All other rules, such as laws for example, are followed to the extent that they are unpunished. Non-gangstas conduct their behavior by the rules they are given.
Gangstas identify themselves with a certain group to which they belong.
They hold the well being of that group superior to the well being of anything else in the world. Despite what may appear temporarily, they only have love for those groups they continually express love for. Sometimes it can be a group of one, in a person that only looks out for themselves. Gangstas are never used or played without their knowledge. Indeed gangstas regardless of the situation, pride themselves on knowing the games around them, and being aware or their circumstances.
