有人知道“掉胃口” 英语怎么说？hang up my stomach??
就是人说话说一半，在激起别人的兴趣的时候就不说了，所以吊胃口用英语怎么说呢？
we have a saying like" hang up my stomach" to describe when people are going to say something interesting, and suddenly stopped for some reason, and it obviously make the person who listens to you a little bit angry, is there a similar English slang for this case? all the answers are appreciated!

Answer

"(pronoun) have lost my appetite"

"I'm sorry I've lost my appetite" 
"He lost his appetite"

Let me see if I can make a story up..

Bob: Hey guess what I saw today Mary?
Mary: What is it?
Bob: I saw this quite interesting show on how cow manure is processed into fertilizer.
Mary: .......(feels like throwing up) .....excuse me, I just lost my appetite (runs to the bathroom)

Answer

you can use the word: tantalize to express. Good Luck.
