Noun
1. A insatiable craving for junk foods.
Ex: I’ve had trash mouth all damn day. I hate Doritios but I can’t stop.
2. Actually have a mouth full of trash.
3. A actual mouth made of trash.
Origin: Chris just started using it one day and it stuck. But it makes sense, junk food is trash food, so a mouth full of junk all day equals trash mouth.
