pass the buck推卸責任。這個習語源自於撲克牌遊戲。為了防止作弊，遊戲的每一輪都要換人發牌。
輪到發牌的人，會拿到一個識別物（稱為buck），所以pass the buck在牌桌上指不擔任發牌的工作，引申為推卸責任。
看看老外聊天時怎麼用pass the buck：
Karen: God! When is the last time you cleaned up the living room?
Jimmy: Don't look at me. I hardly use the living room.
Karen: So it's your roommate? He should clean up the mess.
Jimmy: I' ve told him that. But he always passes the buck.
Karen: If I were you, I would move out as soon as possible.
卡倫：天哪！你上次打掃客廳是什麼時候？
吉米：別看我，我幾乎不用客廳。卡倫：所以是你室友弄的？他真真該清理這些髒亂的東西。
吉米：我和他說過了，但他總是推卸責任。
卡倫：如果我是你，我肯定會儘早搬走。
