Cockfighting
Cockfighting is a blood sport involving domesticated roosters as the combatants. The first documented use of the word gamecock, denoting use of the cock as to a "game", a sport, pastime or entertainment, was recorded in 1634, after the term "cock of the game" used by George Wilson, in the earliest known book on the sport of cockfighting, The Commendation of Cocks and Cock Fighting, in 1607.
