Permanent grin. Usually a result of great fortune arriving in someone's life; a brand new love, winning the lottery (or one of my personal fav's: watching someone illegally passing on the shoulder during rush hour and promptly getting NAILED by the cops.)

An automatic and irremovable smile that appears on the face of people who are thoroughly intoxicated with some narcotic; usually marijuana, hashish, mushrooms, or lsd. Can be found in other cases such as on television morning news anchors, beauty pageant contestants, pop queens, and mental patients.
