核心句型：
He alwyas kisses up to the boss.
他总是拍老板的马屁。
kiss原意“亲吻”，本是表示喜爱的动作，可如果对着一张并不可爱的脸也一脸谄笑地要去kiss，甚至去kiss他的手，他的脚，那就一定是有求于人了。所以kiss up to sb. 这个短语的意思是：“奉承讨好，拍马屁，巴结”。因此，当美国人说:"He always kisses up to the boss."时，他/她要表达的意思就是"He likes to flatter his boss."、"He always sucks up to the boss."、"He seizes every opportunity to curry favor with the boss."。
