When one's scrotum sticks to the inner thighs due to sweating in the groin area. This situation can be nicknamed 'Batwings' because the image created by this scenario can resemble a bat and its wings. The shaft of the penis can be see as the body and the stretched scrotum to either side can be seen as the wings. Many males (and hermaphrodites) find this common occasion displeasing.
-noun. A specific clumsy walk, performed by adult males, that is meant to release his sweaty balls from sticking to the inside of his thighs. This behavior is usually observed right after a man steps out of his truck after a long drive.
Oh man, my balls are sweaty today. I wonder if anyone in this shopping center parking lot notices me doing the batwing shuffle. It worked! That feels good.....
