Ling-Fu is short for Linguistic Kung-fu. It's a term used to describe the abilities of very skilled social engineers, and people who have an uncanny ability to win arguments/sweet talk those around them. If you've ever seen a kid walk into McDonald's, sift through the garbage for empty burger boxes, complain about the quality of food he didn't pay for and then walk away from a smiling register jockey with a full meal, you have witnessed the awesome power of ling-fu. Ling-Fu masters are the guys with the right anwser to everything, or the girl that can participate in a conversation on any subject for an hour. Ling-Fu is a most powerful force, and its students walk amongst us.
