gastastrophe

The passing of extremely pungent gas in a small, socially inappropriate, overpopulated setting. 2-The manipulation of fuel prices to gouge the public for huge profits before leaving political office.

Although the Donald kept his cheeks squeezed tightly together, the fumes building in his stomach from the nachos grande suddenly escaped into the packed boardroom. The gastastrophe made everyone's eyes water.

Gastronomica

The instrument created by your anal cavity; as in 'harmonica'. Making yourself fart. Using the rare ability to suck air up one's anus and farting it out to produce consecutive deep, full tones. >Warning the use of the gastronomica could cause a sudden need to crap.<

Jim Wilson can play his gastronomica like there's no tomorrow. 'Midnight Honkytonk Stroll' by Fecal Spectrum is awesome 'cause they use the gastronomica.
