When any person rips a fart in front of a fan (rotating preferred) while an unexpecting person in the room with you gets to enjoy that sweet sweet anal vapour, hence insta-stink cause it instantly stinks.
While laying in bed with our fan blowing on us I ripped a rather large fart and the insta-stink went up my girlfriend's nose. Who needs the old fashoned dutch oven when you can use this perfect odour enhancer.
