Behind every use there is one simple picture: something that turns and turns until whatever it holds is wound round itself. Hold a wet cloth at both ends and turn your hands in opposite directions, and you have the whole idea. A column of air can do it, and you get a tornado. A person can do it to the facts, bending the story this way and that so nobody can pin it down. A room full of friends can do it to their own arms and legs, and that is a party game. The picture is always the same turn; what changes is what gets twisted.
From the word’s history
The word is twist plus -er, and the form goes back to Middle English twyster, so the parts already carry the picture: the one that twists.
這個字是 twist（扭轉）加上 -er（做這件事的人或東西），來源可追到中古英語的 twyster。字的組成本身就說明了核心畫面：會扭轉的那一個。
