*His Nibs* I don't entirely agree with what is said on the link, in as much as, it needs updating. The sense I was using it in was something I would say if I am being kept waiting, or teasing someone who is not going along with my plan of action etc...It is used in a friendly way these days and is considered quite mild as a prodding instrument. aaah! language! hard to explain sometimes.
