Golfer's nervousness is often referred to as the 'yips' or 'the yips'. The term 'yips' is a four-letter word and 'the yips' is a seven-letter word. The yips is a phenomenon that affects golfers, causing them to experience involuntary muscle spasms in their hands and arms while attempting to make a shot. This can cause the golfer to lose control of their swing and miss the shot. The yips can be caused by a variety of factors, including anxiety, fatigue, and lack of practice. The yips can also be caused by physical issues such as arthritis or carpal tunnel syndrome.
