An physiological test to detect recent forced opening of the anus. Used chiefly on by police to tell if a suspect has placed contraband in their anus, or if a child has been sexually abused. The buttocks are spread lightly apart by to see if the anal sphincter opens after or with the spreading of the buttocks. If so, anal breaching has likely occurred.
As part of his recording contract, Justin Bieber has to pass an anal dilatation test. This time when he bent over in front of the doctors and lawyers, a doctor disappeared! Bieber got a D+, for that one.
