术语是Mysophobia [ maisə'fəubiə ]，意思是不洁恐惧症，通常指的是病态的洁癖，是一种OCD(obsessive-compulsive disorder)。如果只是有一些小洁癖，你可以说neat freak，是指特别爱干净爱整洁的人，例如：Sheldon keeps everything in order. He's really a neat freak.
Neat freaks do not repetitively and obsessively clean things, but they also can get upset when something is out of order because order equals control, hence security.
For neat freaks, order equals control, hence security.
