KK: /ˈfɪdʒɪtər/
A person who often makes small movements with their hands or body because they are nervous or restless.
During the meeting, she was a fidgeter, tapping her fingers on the table and shifting in her seat.
Fidgeter → It is formed from "fidget" (of uncertain origin, possibly from Middle English *fijgeten*, meaning to move restlessly) and the suffix "-er" (meaning a person who). A fidgeter is a person who moves restlessly or cannot stay still.
Think of someone who can't help but move around restlessly — that's what a fidgeter does.
