我們可以用短語 whatever floats your boat 來形容「想做什麼就做什麼，隨意」。
It's your birthday. We can go to the theatre or have a meal in a posh restaurant. Whatever floats your boat.
Peter is a ladies' man but if you still want to go out with him, fine. Whatever floats your boat!
表達 to push the boat out 通常用於慶祝活動的語境中，意思是比以往多花錢熱鬧一下。
We really pushed the boat out and held Mary's farewell party in one of the most expensive restaurants in town.
