大家都很討厭那些說話說一半，吊起別人胃口，然后各種追問都不回答的那種人。這種討厭的行為就是Conversational Blue Balls（對話藍球）。

When someone brings up a topic when talking but immediately drops it and refuses to switch back to the dropped topic, leaving the other hanging in the middle of a conversation. This annoying thing is called “Conversational Blue Balls”.

當某個人談話間提到某個話題而忽然又轉換話題避而不談剛才的話題，把對方的胃口吊在那里。這種討厭的事就是“對話藍球”。（注意是藍球不是籃球哦）

Here is an example of Conversational Blue Balls:

"Goodness, did you hear about what happened?"

"What happened?"

"Anyways, I'm gonna go."

"Wait, what happened?"

"Oh, don't worry about it."

看一個“對話藍球”的例子：

“老天啊，你聽說發生的事了嗎？”

“發生了什么事？”

“沒什么，我得走了。”

“等等，發生什么了？”

“哦，別管那個了?！?/p>

Dude, Jane TOTALLY gave me Conversational Blueballs yesterday. We were on AIM and she asked if I had heard about the party and she never answered when I asked about it.

老兄，簡昨天真是給了我一個“對話籃球”。我們在AIM上聊天時她問我有沒有聽說過關于派對的事，我說沒有，然后我問她派對的事她再也不回答我了。
