Masturbation. A chocobo is a bird-like creature in the Final Fantasy series of video games. Several of these games allow the player to breed different varieties of chocobo. In the online-only Final Fantasy XI the player has to log on and feed his chocobo, or the chocobo will die. How the term became associated with masturbation is unknown.
He was busy feeding his chocobo.
