I put my foot in my mouth.
我说错话了。

这就是当你说了不该说的话时, 突然发觉你说错话了, 就会这么说。有一次我跟老美在聊天, 他跟我说某某人是 Jerk , 想不到他一回头, 那人就在我们旁边。 他就很快说了一句, "I put my foot in my mouth" 。话说我刚学会这句, "I put my foot in my mouth" 后, 我就一直想自己来用看看, 结果呢? 我居然说成了 "I put my foot in your mouth" 结果那个老美笑得合不拢嘴, 他说, "What did you say? You want to put your foot in my mouth?" 真是画虎不成反类犬啊。
