An advancement of the Dutch Oven, the Dutch Sauna starts with either a sauna or a hot shower, or some kind of steamy room. You fart or even shit while in the room. The result, a warm sticky sensation all around you and a more potent fart/shit that will last for significantly longer than average. It may linger in that room for days at a time depending on how long the steam is kept up.
Recommended Application: When your girlfriend/wife is taking a shower, you sneak in and quietly take a shit in the same bathroom as her. Without flushing, exit the bathroom as quietly as possible. By the end of her shower the entire bathroom will be saturated in your ass stink.
