Ghosting is the act of having sexual intercourse with a man or woman with them face first against a window on either the ground floor or with a balcony on the other side. The male carries out intercourse from behind the partner with him/her facing out of the window. He thin pulls out and his mate carries on the act, this should happen quickly so that the partner does not suspect anything.
He then sneaks round to the other side of the window and jumps out shouting "boo". The partner then experiences the true feeling of "being ghosted".

Ghosting is a sport, sometimes described as a paradox, first devised by an Indian dental student. The scenario presents an individual's ability to be metaphysically present and absent in two frames of reference, simultaneously. In the events, one cannot determine with confidence whether one satisfies or nullifies the other. Both events are deemed to be true and witnesses remain in oblivion.
