Definition & Meaning of "smell-feast"in English

What is the origin of the term "smell-feast" and how is it used?

"Smell-feast" is a slang term used to describe a person who is greedy or intrusive when it comes to food or meals. It likely emerged in English in the 18th or 19th century as a vivid metaphor, combining "smell" (the sense associated with appetite) and "feast" (a large meal) to suggest someone who eagerly hovers around food without restraint. The term is mildly derogatory, often used in informal, humorous, or teasing contexts to criticize gluttony or over-eagerness, rather than as a deeply offensive insult.
