I'm afraid not Liz (is that how they call you?). Καταπίνω τη γλώσσα μου is actually when you are speechless or when you have nothing to say literally or as in admitting your guilt or as in trying not to give information.

Thanks very much, Crystal :-)!

I've heard the expression but couldn't remember the precise meaning.
