In popular culture and UFO conspiracy theories, men in black (MIB) are allegedly government agents dressed in dark suits, who question, interrogate, harass, and threaten 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 government UFO secrets or performing other strange activities. They are typically described as tall men with expressionless faces, slightly pale skin, and usually wearing black suits with black sunglasses. "Men In Black" encounters are very common tales told in American UFO conspiracy theories.
