Concert Fart
A fart that is so potent, it will bring one to tears, burn nostrils, and cause heaviness in breathing. This particular type of fart only occurs at a local or relatively large venue while a person is enjoying their favorite musical act(s).
"Hey Joe, why do I suddenly smell Taco Bell combined with a hint of Heineken and fried okra?" "Don't worry Billy, that was just a concert fart."
