"Boo" equivalent in Japanese?


Is there a disappointed or sad "boo" equivalent in Japanese?

Kind of like:

> _Person 1:_ Hey man, can I borrow 10 dollars?  
>  _Person 2:_ Nah, I don't have any change.  
>  _Person 1:_ Boo, now I don't have enough to go to the concert.




I think you could say
「[トホホ](http://dic.yahoo.co.jp/dsearch?p=%E3%81%A8%E3%81%BB%E3%81%BB&stype=0&dtype=0&dname=0ss)」.
It's a lot like "boo hoo". I've heard that it's used more in fiction than in
real life, but I think that's true of "boo hoo", too.

Chocolate pointed out on chat that you could also say
「[あーあ](http://dic.yahoo.co.jp/dsearch?enc=UTF-8&stype=0&dtype=3&p=%E3%81%82%E3%83%BC%E3%81%82)」.
Although I don't see entries for this interjection in any Japanese
dictionaries, you can find it in Japanese-English dictionaries such as
[edict](http://jisho.org/words?jap=%E3%81%82%E3%83%BC%E3%81%82&eng=&dict=edict).
Edict describes it this way:

> oh no (used as an expression of despair or when giving up); sigh of boredom
> or disgust; oh boy

Another related word is
「[がっかり](http://jisho.org/words?jap=%E3%81%8C%E3%81%A3%E3%81%8B%E3%82%8A&eng=&dict=edict)」.
Again, I'll quote edict:

> feel disappointed; dejected; lose heart; feel emotionally drained; feel let
> down

Edict lists more parts of speech for this word than Japanese dictionaries, so
I decided to link to it here. You can say, for example, `がっかりした` or `がっかりだ`. I
think you can also use it as an interjection, though the only place I could
find listing it that way was
[ALC](http://eow.alc.co.jp/search?q=%E3%81%8C%E3%81%A3%E3%81%8B%E3%82%8A&ref=sa):
`がっかり！`
