A person who sets bait to catch animals; someone who taunts or provokes another person deliberately.
From 'bait' (to lure with food, or to provoke) + '-er' (agent suffix). The word has two main meanings: literal (someone who baits traps) and figurative (someone who provokes), with roots in Old Norse 'beita' (to bait/feed).
The word 'baiter' has a fascinating split personality—it can mean someone who professionally catches animals using bait, or someone who deliberately angers others online, showing how one root word can split into very different modern uses.
