Tararí that I saw you : Or I simply hummed, onomatopoeic sound of the trumpet touch, is a colloquial adverbial locution of denial with some nuance of mockery to indicate that the facts happened against what was expected or will act against what was proposed by another. It therefore indicates non-compliance with what is promised or expected or disbelief. It equates to a non-angry or a "nothing, cute" or a "come already" or a "no, man, no." A different sense of expression indicates unexpected surprise.
