High Quality Content by WIKIPEDIA articles! An obscene phone call is an unsolicited telephone call where the caller receives sexual pleasure by delivering sexual or foul language to an unknown called party. Making obscene telephone calls for sexual pleasure is known as telephone scatologia and is theorized as a form of exhibitionism. It is usually classed as a paraphilia from a medical viewpoint, in the DSM under the heading "Paraphilias Not Otherwise Specified", although from the viewpoint of the recipient of the calls, it is generally considered to be both a form of sexual harassment and a form of stalking. In some US states, making obscene telephone calls is a Class 1 Misdemeanor.
