Galo Sengen ("Galish Man GAL" in English / GAL男宣言 in Japanese) is a 2011 rap music video by the Japanese hip-hop group Policeman.
The animated music video became well-known for its humorous depiction of a Japanese youth culture known as "Gyaruo," which is characterized by the dark tanned skin, dyed blond hair and appreciation for dance music.
In the video, a group of men are satirically portrayed as Super Saiyans, a type of superfighters from the Japanese manga franchise Dragon Ball, who transcend into the state of "galish" or "gyaru," a slang term derived from the Japanese pronunciation of English word "girl."
