GuyRule #66.1: Golf's "Practice" Swing
Immediately following a big whiff, a Guy needs to play this off as a Practice Swing. Timing is everything. Adjusting one's grip, tapping the club against the ground, and swinging again will complete the illusion.
If, however, you spin all the way around like a little league girl striking out, then find yourself a skirt and start playing from the red tees.
