Why Do Golfers Yell ‘Fore!’ But Never Other Numbers?

I was watching a golf tournament the other day and heard players shouting “fore!” when a ball went off course. It got me wondering why “fore” specifically? Why not “five!” or even “math!” as a joke? Seems like a missed opportunity for some counting-related humor.

Does anyone know the history behind this? Is there a reason it stuck around while other numbers (or words) didn’t make the cut? Curious if there’s a fun story or just tradition at play here.
