Synonymous with Garbage Gut
Someone who eats poor quality food or junk food often and doesn't give a fuck about it, resulting in obesity, or other various health problems from not eating correctly. Trash guts often like fast food places and they are immune to food poisoning of any kind because they've grown immunities to the bad bacteria by being exposed to them often.

Dude : 2 "You're a trash gut."
