密歇根新闻广播 "gobsmacked"一词的由来（在线收听）

Unless you decided to completely avoid the internet in 2009, there's a good chance you've seen Susan Boyle's first round performance on Britain's Got Talent.

The Scottish singer's rendition of "I Dreamed a Dream" attracted millions of views on YouTube. No one was more surprised than Boyle herself, who told CNN she was "gobsmacked."

Boyle's description of herself caused a bit of a stir among those unfamiliar with this particular British slang term.

To understand the meaning behind "gobsmacked," it helps to know that a "gob" is a mouth. This word comes from Irish and Scottish Gaelic. It still pops up in other places in British slang – for example, "shut your gob!"

If you say that you were "gobsmacked," it means that you were so surprised or astonished, it was as though someone had smacked you in the mouth. It's similar to calling something "jaw-dropping."

Interestingly, "gobsmacked" isn't really that old. During the Susan Boyle frenzy in 2009, Ben Zimmer wrote an article that dated it back to 1956. Since then, the Oxford English Dictionary has updated its entry for this word with evidence that dates it backto 1935.

While Professor Anne Curzan was researching "gobsmacked," she came across some great synonyms, including "flabbergasted." As a verb, we have evidence of "flabbergast" as early as 1773. At that time, it was identified as new slang.

There are different theories as to where this term that's so fun to say comes from.Michael Quinion goes over a few on his blog, World Wide Words.

One possibility is that "flabbergast" was a regional dialect word that got picked up intobroader slang. Another possibility is that it's a blend of "aghast" and "flabby" – basically, you're so excited that you shake.
