Found in  ”Choi Jeong Min” by Franny Choi, “land where they stuff our throats with soil
& accuse us of gluttony when we learn to swallow it” Line 34-35

The definition of the word Gluttony helped me more to understand the meaning of the line. Also, by looking the word synonyms helped me more why actually gluttony was used in the sentence.
