Definition
Vulgarity describes behavior, language, or style that is considered crude, tasteless, or offensive. It implies a lack of refinement and a disregard for social norms. Think of a joke that is inappropriate for a formal setting. Vulgarity can be intentional or unintentional, but it's generally seen as undesirable in polite society. It often offends or shocks others. It's like the opposite of elegance and sophistication. It can be very subjective, depending on the culture.
