An adjective typically used to describe a particularly heinous and unorthodox food crime. Chungy foods are almost always multi ingredient dishes with combinations that no reasonable human being would dare serve to another human being. Sometimes, a bizzare preparation or lack thereof warrants chungy status as well, like a banana eaten with the peel still on, a Turkey cooked in a washing machine, microwaved chicken, or dishwasher lasagna.
A person who repeatedly creates and/or consumes chungy foods may also be described as chungy.
Did you see that 4chan post where the guy made nyquil chicken? That's some real chungy shit.
