I think it is time for a really deep and meanigful topic which gets less attention as it deserved. And I found nothing about it in the internet in my one minute research.
What is tadaaah (as in "tadaaah, surprise!" or when you are proudly presenting something for the first time ) in different languages?
In German is also tadaaa (sometimes also seen with an h)
And I guess in Spanish of Spain it is "tachán!" I f I remember it correctly.
