here is how a treek works……….while you are at a party or visiting someone during the Christmas season, you put a surprise Christmas ornament on their Christmas tree.  the key to treeking them is that you never say a thing.  don’t tell them it is there, or that you did it.  Then when they notice the strange or unusual ornament, they will wonder where it came from and who put it there.  how fun is that?   Secret Santa meets Ugly Christmas Sweater in one great prank that is personal, fun, hilarious, and totally a secret.
