Something or someone that bites or chews vigorously, often used to describe teeth or a device that crushes things.
From 'chomp' plus the agent suffix '-er,' making it something that performs the action of chomping; became common in 19th-century industrial vocabulary.
Wood chippers, industrial crushers, and even playful names for people with big teeth all use 'chomper'—it's a wonderfully flexible word that applies wherever something bites or crushes.
