What does cruddy mean?
"Cruddy" is an informal adjective describing something covered in dirt, grease, or an unpleasant film — a cruddy pan, a cruddy windshield, a cruddy old engine part. By extension it also characterizes anything of poor quality: a cruddy restaurant, a cruddy haircut, a cruddy piece of software. The word derives from "crud," a noun meaning filth or dried residue, which itself has roots in Middle English and gained colorful new life as mid-twentieth-century military slang for various ailments and messes. Because it carries a mildly disgusted tone without being vulgar, "cruddy" sits comfortably in casual conversation, complaint, and humor. It is most at home in spoken and informal written English, where its blunt, slightly comic sound makes it a favorite for expressing dissatisfaction with both grime and general shoddiness.
