Someone who will often appear next to you without warning. This is often done in silence and when you turn around that person would be next to you. They also often butt into conversations the moment you finish talking.
Adam is such a siddler. Whenever I'm talking to Aidan he just appears and starts talking the moment I finish. I never have any clue when he will be next to me.
