Hairy arm is an underhanded technique for finishing films or videos quickly. Most editing sessions are expensive and require a long approval process before the film is considered complete. Often the people who have final say over the aesthetic content of a film or video are not present during the actual editing process; to get approval quickly, an editor may throw in an intentionally awful or incorrect shot, simply to distract the attention of the "approver" away from harder to define deficiencies in the final film or video.
