when browsing the intarwebs for information or opening a file on your computer and the link is slow: when you click on it, you begin to click multiple times over and over and over thinking that it will make the hourglass go away and bring up the program/website faster.
IT guy: Dude, that lady over in HR is at it again, she thinks that the network is down because she can't open her 500meg word document full of pictures and links. When I got to her desk she was clicking away faster than someone playing Halo.
