1. Ass backwards 搞错了，搞反了
You installed these windows ass backwards - the screens should be on the outside!
你把窗户安反了，玻璃应在外面。
释义：
ass: 臀部，屁股
backwards: 向后，相反
ass backewards: 倒骑驴
2. Ass-kisser 马屁精
Peter is such a typical ass-kisser and he is always telling the boss how great he is.
彼得真是个不折不扣的马屁精，就只知道恭维老板。
疯狂联想：
ass: 臀部，屁股
ass kisser: 恭维别人，拍马屁的人
