the testifyer is given when the man squats over the womans asshole while she lays on her back with the legs above her, near her head. The balls and cock are inserted into the womans fuck holes and then are "pumped" multiple times.
Aww nigga, I used the testifier on this bitch last night and she farted on my left nut. It hurt like getting a cumshot to the eye.
