Date rape is a form of acquaintance rape. The two phrases are often used interchangeably, but date rape specifically refers to a rape in which there has been some sort of romantic or potentially sexual relationship between the two parties. Acquaintance rape also includes rapes in which the victim and perpetrator have been in a non-romantic, non-sexual relationship, for example as co-workers or neighbours. Date rape is particularly prevalent on college campuses, where it frequently occurs in situations involving alcohol or other date rape drugs, which may facilitate the execution of drug facilitated sexual assault (DFSA).
