buffed

The modern informal sense of 'buffed' meaning muscular is a fascinating semantic evolution. It stems from the earlier verb 'to buff', meaning to polish leather to a smooth, shiny finish. This polishing action metaphorically transferred to the process of working out to make one's body smooth, shiny, and well-defined. The connection to 'buffalo' leather provides a tangible origin, with the strength and toughness of the animal's hide subtly reinforcing the later association with physical power and a hardened physique. Thus, a 'buffed' person's body is perceived as being polished and perfected like fine leather.

The word 'buffed' is the past participle and adjective form of the verb 'buff'. The verb 'buff' (to polish or make smooth) originates from the noun 'buff' (a soft, pale yellow leather), which came from 'buffalo'. The ultimate origin is the Italian word 'bufalo', meaning buffalo, from Late Latin 'bufalus', a variant of Latin 'bubalus' (wild ox, antelope).
