scrot vino
After exercise, clubbing or just walking around, the testicles accumulate a certain amount of sweat, or 'wine'. Said fluid is known as 'scrot vino', as in the wine from a scrotum. Vino tasting occurs when a particularly sweaty man cups his testicles, catches a layer of vino and cups someone's nose.
