gonzo 

A style of porn shooting where the camera is hand held, often very close and intimate with the performers, and the fourth wall is often broken (performers may address the audience directly, admitting that a camera is present).

Gonzo porn is often characterized by fast camera movements, hand held camera shots, and segments shot in strange places, often public or semi-public. The style tends to be more in your face, and very raw. Gonzo porn movies often go a long time on a single camera shot, with the camera moving rather than edits occuring.

Gonzo porn and reality porn are often intermixed and confused with one another, as they often have similar styles of production and story lines.
