Who is secret Santa?

Secret Santa is usually a gift-trading game that people play. Everyone puts their name in, and then each person draws a name to give gifts to. They drop the gifts by when the person isn't there, and so it stays secret. Usually they find out at the very end, when people tell each other who they were giving gifts to. :) It doesn't really have anything to do with Santa himself, but it is just inspired by his flair for generosity.
