An advancement of the Dutch Oven, the Dutch Sauna starts with either a sauna or a hot shower, or some kind of steamy room. Then, you fart, piff, rip-ass, blow a fatty, or even shit while in the room. The result will be a warm sticky sensation all around you and a more potent fart. This will last for significantly longer than your average fart. It may linger in that room for days at a time depending on how long the steam is kept up. Enjoy.
While my brother was in the shower, I ran into the bathroom and gave him a Dutch Sauna and he screamed.
