Slate's Kevin Arnovitz reveals some of the jargon he learned on the "set" during his brief stint as a "writer" on a reality TV series. One example:
OTF (n) ["On the Fly"]: A quick, impromptu interview of a reality show contestant intended to convey the contestant's emotions and actions in the moment, as opposed to the more reflective sit-down interview. An OTF is always shot with a handheld camera, sometimes even in motionówhile walking and talkingóand often in a moving vehicle.Virtual Dictionary - a guide to the language of reality TV [Kevin Arnovitz, Slate]
