Gastronomical determinism 

Where the duration of a meeting is extended for no reason other than to include a free lunch or dinner.

The meeting went on an hour longer than it had to. Gastronomical determinism ensured that the debate continued, focusing on meaningless issues, until the company provided lunch was served.

Gastropolitan 

Somebody who's super morbidly obese to the point of probable near-death, but acts sexy as fuck and tries to guilt everybody else into finding them attractive.

Have you heard that Tess Holliday made the cover of Cosmopolitan magazine? Looks like "Gastropolitan" is a whole new level of Cosmo.

gastrology 

A science based on an ancient system of divination, consisting primarily of pulling a horoscope out of one's ass.

During my first year at gastrology school, I mostly studied the signs of the zodiac, creative composition and ass-based fortune telling.
