How does one tell a Gansta from a Grandsta? A Gangsta will wear a short shirt and the top of his pants halfway down his ass. He will usually have an underwear look sewed between. Whereass, a Grandsta will wear a short flannel shirt and the top of his baggy pants halfway down his ass, with an underwear look between them...with a flap.
