is when you take an object and thrust it into the "ecess" space in the triangular like shape formed when a person is in a sitting position on a chair and the two cheeks of the butt are visible. You must aim between the cheeks and thrust the object there.
Chris sits down in a chair, Stephen walks behind and quickly thrusts the object into the triangle zone causing an uproar in Chris's Anus.
