玩过扑克poker的人都知道
玩扑克有时候你就是得诈
明明一手烂牌
也要虚张声势表现出自己的牌超好的样子
虚张声势，吓唬人用英语讲叫bluff
可有些人就是不相信你的bluff
非要揭穿你
这样的行为就叫
call one's bluff
也就是揭穿某人的虚张声势
戳某人老底的意思
例句：
1. I told my parents that I had gotten passing grades in
all my classes, but they didn’t believe me. They called
my bluff and asked to see my report card.
我跟我爹娘说我考试都通过了，但他们不信，非要揭穿我，要看我的成绩单
2. The bank robber threatened to shoot the bank guard,
but the guard called the robber’s bluff by walking up
to him and taking away his gun.
银行抢劫犯威胁要对银行保安开枪，但是保安才不鸟他的虚张声势，走过去就把他的枪给夺过来了
