The slang(?) phrase "乾掉了" As I remember, the phrase was used in response to a certain scenario. Unfortunately, as I tried to look it up on Google, all I find is drying out, which is certainly not the meaning I am looking for. Thus, my take is that this phrase is probably a slang.

Besides, I am not familiar with Simplified Chinese so I could be wrong, but this slang phrase seems to exist only in Traditional Chinese. Among the search results in Simplified Chinese, all I see is 干掉, which means to kill/eliminate, but as far as I know, 乾 means dry.

That said, I assume it is a slang phrase used in colloquial context. But apart from the drying out definition, what could it mean? 

Thanks in advance!

EDIT:

I think it might be in response to some joke. The context was something like:


  uh...乾掉了...


That's all I could remember... Any help is appreciated.

EDIT2:

According to @sonyuanyao's comment, this phrase is often used in Taiwanese TV show and possibly means not funny or embarrassing.
I think is a slang in Taiwan

乾掉了 mean something is turning into boring(usually use after someone say a not funny joke) or the situation that people don't know what to say or react to it

ex1:

You just meet someone new to you

after greeting, you don't know what to say to him, and so does he

this embarrassed situation can be said "乾掉了"

ex2:

you are holding a show and after talking a joke

you are waiting crowd to laught

but there's no one laughing, and a embarrassed silence appear

you can say "this show 乾掉了"
