KK: /ˈhændˌrɪŋɡər/
A person who shows a lot of worry or distress by squeezing their hands together.
During the meeting, she was such a handwringer that everyone noticed her anxiety.
Handwringer → The word is formed from "hand" (from Old English "hand", meaning the part of the body at the end of the arm) and "wringer" (from the verb "wring", meaning to twist or squeeze). A handwringer refers to a device or action that involves twisting or squeezing by hand, often to remove water from wet clothes.
Think of using your 'hand' to 'twist' or 'squeeze' something — that's what a handwringer does.
