What does crummy mean?
"Crummy" is an informal adjective used chiefly in British and American English to describe things that are of poor quality, shabby, dirty, or otherwise disappointing. A crummy hotel is run-down and unappealing; a crummy job pays badly and offers no prospects; crummy weather is grey, wet, and miserable. The word can also be applied to people, though in this case it typically describes how someone feels rather than who they are: a person who is "feeling crummy" is under the weather, tired, or generally out of sorts. The term carries a dismissive, mildly negative connotation and belongs firmly to casual conversation rather than formal prose, where words like "inferior" or "substandard" would take its place. Its origin is surprisingly humble: "crummy" derives from "crumb," the small fragment of bread, and originally referred to something littered with crumbs before evolving into a general byword for anything worthless or second-rate. That everyday pedigree makes it a vivid, relatable word for expressing dissatisfaction.
Of poor quality, unpleasant, or inadequate; dirty, shabby, or generally unsatisfactory.
"He spent the summer doing crummy odd jobs around town to save up for a car."
Informal register; often used for accommodation, weather, food, jobs, and general circumstances.
(Informal, of a person) Feeling unwell, out of sorts, or generally below par.
"She stayed home from work because she'd been feeling crummy since the weekend."
Refers to physical condition rather than character; common in conversational American English especially.
"Crummy" literally began life as a word for bread scraps — it comes from "crumb," so calling something crummy originally meant it was covered in worthless little bits.

Etymology of crummy
"Crummy" originates from "crumb," an old English word for a small fragment of bread, which itself traces back through Old English "cruma." In its earliest recorded uses, "crummy" described something covered in or full of crumbs — a crummy tablecloth was one littered with bread fragments. Over time, likely by the nineteenth century, the sense broadened: since crumbs were seen as worthless scraps, anything shabby, dirty, or of poor quality came to be called crummy. A closely related spelling, "crumby," shares the same derivation and meaning, though "crummy" has become the more standard form.
How crummy is actually used
Primarily informal and colloquial in both British and American English; common in everyday speech but rare in formal writing. When applied to people, it usually refers to how they feel physically rather than their character. The related spelling "crumby" exists but is less standard for this sense.
