chimp v. to take a digital photo and look at it on the camera’s screen. Editorial Note: The term probably comes from scornful references to amateur photographers as “chimps,” a term which is used in other contexts to mean a fool or stupid person and here specifically means a person who does not really know how to take good photographs.

I first heard “chimp” as a verb to describe the fingering action one uses whe operating cellphones and other like gadgets more than five years ago.
