Dragon Burp 

When you drink a fizzy drink so fast that you cant hold the bubbles in anymore. They exit through the nose and leaving a path of burning destruction behind them. Often leaving the drinker with singed nasal hair and watering eyes.

Dragon Burp 

Another name for Sulphur Burps where the body via multiple different situations produces hydrogen sulfide in the form of a burp that is both highly flammable and smells of Sulphur (bad eggs). The name comes from many "scientific" explanations of Dragon Breath being a burp of sulphuric gas ignited by some source.
