grow teeth
v. phr.— «The 16th can change character daily. It can be relatively benign if there’s no wind blowing. But put a breeze in the golfer’s face and the 16th grows teeth. The lake and a big tree at the corner of the slight bend come into play on the right side of the tee.» —“Players still sweet on No. 16″ by Jon Roe Star-Tribune (Minneapolis, Minnesota) June 12, 1991.
