What does chummed mean?
'Chummed' is the past tense and past participle of the verb 'chum', which has two distinct uses. In its older and more familiar sense, to have chummed with someone is to have been their close friend or companion; in British school and university tradition, students who 'chummed together' shared rooms as well as friendship, giving the word an air of camaraderie and youthful intimacy. The verb is informal and carries a warm, slightly old-fashioned connotation — phrases like 'chummed up with' survive in colloquial speech, but the term can sound quaint to younger ears. Separately, in angling jargon, particularly North American, to have chummed the water means to have scattered bait or groundbait to attract fish. This second sense developed independently and has nothing to do with friendship, making 'chum' a genuine homonym in practice. The word is useful for evoking easy companionship in narrative writing.

Etymology of chummed
The noun 'chum', from which the verb derives, first appears in English in the late 17th century as student slang for a room-mate, and is generally thought to be a contraction of 'chamber fellow' or a similar dormitory phrase. From the room-sharing sense it widened to mean any intimate friend by the 18th century, and the verb followed. The unrelated fishing sense of 'chum', meaning bait scattered on water, emerged separately, likely from Algonquian-influenced American maritime vocabulary, though its exact origin is uncertain.
