What does chestiest mean?
"Chestiest" is the superlative of "chesty," an informal adjective with two distinct senses depending largely on where English is spoken. Its older sense describes someone with a large, broad, or prominent chest — a deep-chested, powerful build often admired in athletes such as rowers or swimmers. In British English, however, "chesty" more frequently refers to congestion: a chesty cough produces thick mucus in the lungs rather than a dry tickle in the throat, so calling someone the "chestiest" patient in the ward suggests they are suffering the worst respiratory symptoms. The word derives ultimately from "chest," via Old English and Latin roots relating to a box or container. Because it is colloquial and somewhat old-fashioned in its descriptive sense, "chestiest" rarely appears in formal writing, but it remains vivid and immediately understood in both athletic and medical contexts.
Most full, broad, or prominent in the chest; having the deepest chested build.
"He was the chestiest wrestler in the heavyweight division."
Typically used informally when comparing physiques.
(British informal) Most prone to or affected by chest congestion, as in a chesty cough.
"The doctor said she was the chestiest child on the ward that winter."
Primarily British usage; Americans would more likely say 'congested'.
One word, two very different jobs: in America "chestiest" praises a broad-shouldered swimmer's physique; in Britain it might describe the worst cough at the doctor's office.

Etymology of chestiest
"Chestiest" is formed straightforwardly as the superlative of "chesty." The base word "chest" comes from Old English "cest" or "cyst," meaning a box or receptacle, which itself was borrowed early into Germanic languages from Latin "cista" (a basket or box, ultimately from Greek "kiste"). The anatomical sense — the part of the body enclosed by the ribs — developed naturally from the idea of the torso as a container. The adjective "chesty" emerged in the nineteenth century, giving rise to comparative and superlative forms like "chestier" and "chestiest." Cognates of the root include "cist" and, more distantly, words like "cassette."
