What does rotter mean?
A rotter is a person regarded as contemptible, dishonest, or despicable. The word belongs chiefly to informal British English and is now more likely to sound theatrical, archaic, or deliberately rude than merely descriptive. It often appears as a direct insult, as in “you rotter,” and traditionally conveys moral condemnation rather than ordinary criticism. Historically, “rotter” could also denote something subject to decay or a person who literally rots, but those senses have largely fallen out of use. In modern fiction and historical dialogue, it can efficiently characterize someone as a villain or scoundrel while adding a distinctly old-fashioned dramatic flavor. It should be avoided in formal or neutral contexts because of its insulting force and potentially outdated British register.
