snapmatic

A digital photograph taken within a video game. Coined by Rockstar Games in GTA V the term has become synonymous with any video game photos. Very popular past time for Instagram/ Twitter douche bags with too much fucking time on their hands and genitals.

I took this awesome snapmatic yesterday of the new DLC car in GTA. If you look closely you can see my desperation for actual good content hidden subtly in the background.
