Someone who has a very rare ability to say all the right things at the right time. Even when a situation is not in their favor, by the end of the night their uncanny ability with words has turned a unfavorable situation into an advantage. They are charming and possess all the people skills then some, they can talk their way out of or in into anything they want. Even more deadly if the person is hot. Basically they can sell a ketchup Popsicle to a woman wearing white gloves.
