KK: /ˈflɪnʧər/
A person who reacts with fear or surprise, often by moving away quickly.
During the scary movie, he was such a flincher that he jumped at every loud noise.
Flincher → The word 'flincher' is derived from the verb 'flinch' (from Middle English 'flinchen', meaning to shrink back or recoil) combined with the suffix '-er' (meaning a person who). A flincher is a person who shrinks back or recoils from something.
Think of someone who 'shrinks back' when faced with something scary — that's what a flincher does.
