look up any word, like plopping:
 
1.
When your just stolling along minding your own business when all of the sudden u notice a group of people posing for a picture and you have to stop to avoid being in the picture. This event commonly occurs by tourists and asians in citys or theme parks. A request that you take a picture so the photographer can get in the picture may also be made.
I strolling down times square when I had to do a photostop to avoid getting some tourists picture.

Jim: Hey joe why are you so late?

Joe: I had like 5 photo stops on the way here, this place is flooded with asians!
