In English, for instance, one might say "Thanks for nothing". Is there anything like this in French - would it even be the same?
Just a side note: I have heard a term which I cannot spell and have not seen written; it sounds something like "jour merci", but of course that would make no sense. I considered 'dieu merci', but in the context it did not make much sense either.
In this prank video, for instance, at around 7:19 I hear this phrase and although the captions are heplful for the translation I would like the French words to go along with it.
Thank you in advance.
