armenian sauna
While your in the shower with another person, preferably of the opposite sex, and when the shower gets really hot and steamy you let out a nasty fart. The fart clingings to the steam and you force the other person to breathe in your fart. Some say you can even taste the fart. i e. its the dutch oven of the shower.
To piss off your girlfriend, you fart in the shower putting her in an armenian sauna
