My younger sister is a greedy guts… she keeps eating whatever she finds until she is sick!
There are several types of greedy guts: some like to have too much food, some like to have too much wealth, and some others go to any length for fame.
Though greedy guts is an insulting term to be used for a person, there several restaurants, eateries and packed food items that are named ‘greedy guts’, and people eat in those eateries and buy and eat those packed items like real greedy guts!
