Brass Cupcake means: Predisposed to live in fantasy-like states that lead to inappropriate behavior in public. This includes drug abuse or geeky, flamboyant and self-indulgent avocations. A thing that is blatantly stupid, overly planned or indulgent. As a qualifier, the term “real” is often used with it to denote extreme cases where someone feels the need to draw negative attention to himself. However, by doing this, they try to instill or force identification to the target audience for which the characteristic, mannerism, or activity was intended.
