See rape; a criminal offense. An act of rape occurring during a voluntary meeting of two persons for social purposes which ultimately leads to unwilling, forced sexual intercourse. May also refer to rape by the use of a narcotic which the victim unknowingly ingests (a date rape drug) which also leads to involuntary sexual intercourse. The distinction made in this instance is that a crime has been committed despite the fact that the parties voluntarily agreed to meet for social purposes and may have prior known each other.
