To bite or chew something noisily or with force; to snap at something with the teeth.
An imitative or onomatopoetic word, possibly influenced by 'champ' (an older word meaning to bite or chew), popularized in American English in the early 20th century.
The word 'chomp' actually sounds like what it means—'chomp' has hard consonants that imitate the sharp bite, while 'nibble' has soft sounds reflecting a gentle bite. English is full of these onomatopoetic words that sound like their meanings!
