Chimping is the name for admiring your own photograph on the LCD screen of a digital camera after you've taken a shot. I did not know why this term was used until I watched this 8 minute quicktime movie about chimping. It's in two nearly 40 megabyte parts, so be patient while you download it with your cable or DSL. (Sorry Z, watch it at work. Turn the sound low and try not to laugh loudly.)
For an easier download, here's Mr. Black. No chimp.
