It is "Fore", not "four", hence not "five" either. The "Fore" comes from the old use of "Fore-caddies" who were down the fairway looking for the golfers ball coming down the fairway from the tee. The golfer would yell "Fore" telling the "Fore-caddie" that the ball was on the way. Now, of course, "Fore" means "Watch out! Ball is coming your way."

"Fore!"
As today players many years ago had caddies, and each caddy had a "forecaddy", the forecaddy would assist the caddy. The forecaddy would stand out in the fairway and wait for the balls to be hit from the tee, so they could be found. As soon as the player hit the ball, the caddy would shout "fore", a shortening of the word forecaddy, to let him know the ball was coming.
Fore shouted in a round of golf to alert other players you ball is heading near them, and warning them to protect themselves.
