Comparative form of crummy; more poor quality, unpleasant, or undesirable than something else.
Regular comparative form created by adding '-er' to the adjective 'crummy,' which itself derives from 'crumb' and came to mean shabby or inferior by the early 20th century.
Interestingly, 'crummy' started as a literal descriptor of breadcrumbs but shifted to mean 'inferior quality'—probably because crumbs are small, scattered, and left over from something better.
