One who sneaks into the background of a person or group of people
posing for a picture, usually making a face or picking their nose, totally
unbeknownst to the photographer.
Sometimes, the
savvy photo-imposer will even squeeze in with a group of friends posing for a *guest phtographer.
Guy showing off pictures at work- "Here we are in New York, see
the Statue of Liberty behind us?"
Co-worker- "Yeah, but whos that guy next to you scratching his nuts?"
Bill: Here we are at
Joe's party, what a blast!
Dave: Who the hell is the guy next to you putting his
tounge in your ear???
Bill: Damn photo-imposer, Janet said he grabbed her ass during the picture.
