UK: tʃæmp | US: tʃæmp
n. 1. (informal) A champion.
vt. 2. To bite or chew noisily.
vi. 3. To show impatience or eagerness (often with "at the bit").
The word "champ" originates from Old French champer ("to bite"), likely imitative of the sound of chewing. Its informal noun sense meaning "champion" arose in the late 19th century as a shortened form, reflecting the victor's metaphorical "bite" at success. The phrase "champing at the bit" (eager/impatient) derives from horses noisily chewing their bits.
