What does champ mean?
Champ serves two distinct purposes in English. Most commonly today, it functions as an informal noun meaning a champion — a person who wins a competition or holds a title, as in 'the defending champ' or 'a local tennis champ'. This usage is casual and friendly, appearing frequently in sports commentary and everyday conversation. Less familiar to many speakers is the older verbal sense: to champ is to chew food noisily and persistently, a word often applied to horses grinding on their bits. From this image comes one of English's most vivid idioms, 'to champ at the bit', meaning to be impatient or eagerly waiting to begin something — originally describing a restless horse biting down on the metal bar of its bridle. Whether praising a victor or describing barely contained eagerness, champ adds color and energy to speech, bridging sporting slang and centuries-old equestrian imagery.
Informal short form of 'champion': a person who has won a competition or contest, or who excels at something.
"After three straight titles, he was widely hailed as the undisputed champ."
Informal register; common in sports contexts.
To chew or bite food noisily and repeatedly; figuratively, to display impatience or restless eagerness, chiefly in the idiom 'champ at the bit'.
"The horses champed at their bits, eager to begin the race."
Standard plural for the informal noun meaning 'champions'.
"Both champs will defend their titles next season."
The phrase 'champ at the bit' comes from horses actually biting down on the metal mouthpiece of their bridle when impatient — so every time you say it, you're comparing yourself to an eager racehorse.

Etymology of champ
The verb 'champ' entered Middle English in the late medieval period, likely imitative or of Germanic origin, meaning to bite or chew. It is unrelated etymologically to the noun sense: the informal noun 'champ', short for 'champion', derives from the Latin 'campus' ('field'), the same root that gives us 'campaign', 'camp', and even 'champagne' — named for the open plains of the Champagne region of France. The two words thus arrived at identical spelling by entirely separate routes.
How champ is actually used
As a noun meaning 'champion', 'champ' belongs to informal and sporting registers ('the defending champ'). The verb sense describing noisy chewing is somewhat old-fashioned and literary, though it survives robustly in the idiom 'champ at the bit'. Note that both 'champ' and 'chomp' are heard in that idiom, with 'champ' regarded as the traditional form.
Easily confused with champ
'Chomp' means to bite or chew vigorously and is now largely interchangeable with 'champ' in chewing senses, but only 'champ' appears in the idiom 'champ at the bit'; 'chomp at the bit' is a common variant considered nonstandard by many style guides.
'Champ' as a noun is simply an informal short form of 'champion', which is the full word for a winner or advocate.
