In popular culture and UFO conspiracy theories, men in black (MIB) are government agents dressed in black suits, who question, interrogate, harass, threaten, allegedly memory-wipe or sometimes even assassinate unidentified flying object (UFO) witnesses to keep them silent about what they have seen. The term is also frequently used to describe mysterious men working for unknown organizations, as well as various branches of government allegedly tasked with protecting secrets or performing other strange activities.
The term is generic, as it is used for any unusual, threatening or strangely behaved individual whose appearance on the scene can be linked in some fashion with a UFO sighting.[1] Several alleged encounters with the men in black have been reported by UFO researchers and enthusiasts. The "MIB" supposedly appeared throughout different moments in history.
Stories about men in black inspired the science fiction comedy franchise Men in Black, and an album by the Stranglers.
