note: This takes some planning, a pair of nylon gym shorts, and willing ..or unaware partner to work. When a guy has been doing an athletic activity and has swamp-sack (foul smelling scrotum) he will close one leg opening tight and then he gets his significant other to blow air up his shorts only to have the air circulate and exit back out the same leg hole into her/his face.
I plopped down on the couch after finishing my run. I told "Jane" my nuts were hot so she decided to blow up my short to "cool them off" but I closed off the other leg and she got the "Sweaty-Sack BackDraft"
