A slang term for the San Francisco Giants, the word "Giants" starts with "G", and all the players on the team are male, thus you get the term "G Men". This term was popularized by a remix of the song "Fly Like a G6" called "Fly Like a G Men", celebrating a Giants victory. The term "G Man" is derived from this word, and refers to an individual player from the team.
