The term Men in Black (MIB), in popular culture, is use in UFO conspiracy theories to describe men dressed in black suits claiming to be government agents who attempt to harass or threaten UFO witnesses into silence. "All MIB are not necessarily garbed in dark suits," writes American writer Jerome Clark. "The term is a generic one, used to refer to any unusual, threatening or strangely behaved individual whose appearance on the scene can be linked in some fashion with a UFO sighting."
