Exhaust of the dragon
Most folk who are not familiar with the skill "Exhaust of the dragon" assume that a practitioner would breathe fire out of their mouths. Those that have learned the skill know just how wrong that is. But in order to avoid embarrassment when using the skill, you will often see the person bend over slightly and open their mouths. What actually happens is known in semi-polite society as a "fart". The exhaust of a dragon is a fragrant collection of smells intended to lie an opponent low.
