A "Brotograph" is a picture where the subject (usually male) is shown dressed in frat clothing or acting in a manner consistent with the stereotypical frat-boy image. Elements included in the image may include beer pong, popped collars, and upside-down visors. The term "brotograph" is a combination of "photograph" and the oft-used frat-boy greeting "Bro".
Tyler stopped the game of beer-pong for a second to grab his camera.
