In the game of Golf, a Divot is the name given to the chunks of turf that are ripped from the fairway when a stroke is set too low, and a slice of the grass takes flight along with the ball.
Though divots are most commonly associated with hackers, Dannye informs me that is usually the inexperienced golfers who don't make divots, whereas the pros almost always do, as can be frequently observed on televised golfing tournements.
It's usually not a big issue if you make a divot, just make sure you Replace your Divots!
