Someone who in a stealth like performance drinks the milk, someone who is very Jedi when it is time for mass amounts of milk to be moved.
"MOM: Where the fuck did all the milk go?" SON: "I dont know I havent had any" all in the while he is smiling with complete accomplishment in his head, just like a true MILK-NINJA
