我觉得passive-aggressive就是说话办事阴阳怪气的；有事不直说，等你去领会。查了WiKi：

of or denoting a type of behavior or personality characterized by indirect resistance to the demands of others and an avoidance of direct confrontation, as in procrastinating, pouting, or misplacing important materials.

又，WiKi 太有用了，还没广告。如今每年给他们捐一点儿钱。
