First Guy: "Then, Tommy's friend just popped up out of nowhere and started listening to our conversation, no idea how long he was standing there."
Second Guy: "Then he disappeared next time you looked over?"
First Guy:"Yeah, how did you know?"
Second Guy: "He's an Awkward Ninja"

similar to the awkward turtle, place your hands on top of each other, except point your palms towards the awkward individual (representing the evolution of the ninja turtles to walk upright) and make punching/kicking gestures with your forefingers/thumbs
