核心句型：
He alwyas kisses up to the boss.
他總是拍老板的馬屁。
kiss原意“親吻”，本是表示喜愛的動作，可如果對著一張并不可愛的臉也一臉諂笑地要去kiss，甚至去kiss他的手，他的腳，那就一定是有求于人了。所以kiss up to sb. 這個短語的意思是：“奉承討好，拍馬屁，巴結”。因此，當美國人說:"He always kisses up to the boss."時，他/她要表達的意思就是"He likes to flatter his boss."、"He always sucks up to the boss."、"He seizes every opportunity to curry favor with the boss."。
