to play就是：玩，fast就是：快，loose用在這里，它的意思就是：輕率的，不在意的。要是說一個人play fast and loose，那這個人就是不負責任的，靠不住的，反復無常。
【例句】
He had been allowed to play fast and loose long enough.
大家容忍他反復無常地玩弄手腕夠久啦。
I feel sorry for Mary. Jim has been playing fast and loose with her affections too long. Why doesn't she make up her mind once and for all, and just get rid of the man?
我真是替瑪麗感到難受，因為吉姆長期來對她的感情毫不在意。她干嘛不干脆下定決心和他分手算了？
