A lot of people get nervous when it comes to this but it's really easy! All you have to do is when you walk next to him or just stand with him brush your hand against his "accidentally" as many times as needed. Then look down a couple times, and glance at your guy's hands for a couple seconds. When you look down, it makes him think you can't see him so he looks at you out of the corner of his eye. He'll see you looking at you hands and when you do that added with the hand brushing, he'll definately get the hint and make his move.
