means Athletes who fight one another with padded fists under formal rules, or alternatively a loose-fitting style of men's undershorts named for their resemblance to the trunks such fighters wear.

from From "box," a verb meaning to strike with the fist, attested in English since the 1500s though its ultimate origin is uncertain — it may be related to an older sense of "box" meaning a blow or buffet. A "boxer" became one who fights this way. The underwear sense is a 20th-century borrowing, named because the shorts looked like a prizefighter's trunks. The dog breed, incidentally, likely earned its name from its habit of "sparring" with its front paws.
