The act of dropping one's trousers/shorts with the intention of exposing one's inner thigh's/genitals to the wind.
Usually done in hot or stuffy climates.
The result is probably the most refreshing thing one could do while sweating profusely
N.B. Can be an extremely risky action in crowded areas as one may be mistaken for a pervert.
Not recommended in public places.
Ex.1 - I was so hot in that sun I had to drop my pants for a bit of windies. I've never felt more refreshed.
Ex.2 - Sorry I had to leave for a minute, my balls were sweating so bad I had to find a secluded area for some windies.
