跟心儀的人面對面的時候，我們經常不知所措，那些浪漫的詞語一個都想不起來，等人家走了，腦子里才開始涌現各種連珠妙語。我怎么早沒想到這些呢？嗯，這就是conversational remorse。還有那些吵完架才想出來該怎么回嘴的，也屬于這一類。

Conversational remorse is the feeling you get after leaving a conversation and thinking of all the things you should have said when you were in the conversation, be it witty feedback, wise advice or informative message.
Conversational remorse指跟別人說完話，你才想起來之前應該說的都沒有說，這些談話過后才想起來說的可能是機智的回擊，英明的建議或者有用的信息。

因此，我們可以把conversational remorse稱為“聊天懊悔”或者“聊天馬后炮”。

For example:

I should have said NO to all her requests, but that was too late, there is only conversational remorse left in me.
我應該拒絕她的所有要求，可惜一切都太晚了，我只能在這里馬后炮。
