Narrative

AFTER LNDG AT DFW RWY 31R; HELD SHORT OF RWY 35C ON TXWY Y. ACFT AHEAD WAS CLRED TO CROSS RWY 35C AND THE REST OF THE XMISSION WAS BLOCKED. ASSUMING IT WAS CLRNC FOR US TO CROSS AS WELL AND NOT WANTING TO DELAY TFC BEHIND US THAT WAS ALSO WAITING TO CROSS; I ASKED THE FO TO VERIFY THE LAST. THE FO ASKED THE CTLR WE ARE SHORT OF RWY 35C AT TXWY Y AND UNDERSTAND WE WERE CLRED TO CROSS RWY 35C TO HOLD SHORT OF RWY 35L. THE CTLR ANSWERED ANOTHER CALL THEN TO US SAID THAT IS CORRECT. MY FO ACKNOWLEDGED SIMPLY WITH ROGER; WHEREUPON I STARTED TO CROSS BUT INSISTED THAT THE READBACK BE REPEATED INCLUDING THE RWY WE WERE XING AS WELL AS THE RWY WE WERE TO HOLD SHORT OF (PRIMARILY BECAUSE SEVERAL CALLS HAD BEEN BLOCKED). I HAD CROSSED THE HOLD BARS BUT STOPPED SHORT OF THE RWY WHEN THE CTLR YELLED AT US AND LANDED SEVERAL ACFT ON RWY 35C REFUSING TO ANSWER MY RADIO CALLS TO CONFIRM THAT THE TWR KNEW WE WERE OVER THE HOLD BARS. THE CTLR WAS MAKING UNJUSTIFIED REMARKS THAT AGGRAVATED THE SIT. AFTER HEARING THE TAPE IT TURNS OUT THE CTLR HAD STEPPED ON OUR XMISSION THAT STATED OUR POS BEFORE HEARING THE REST OF THE SENTENCE THAT WE UNDERSTOOD WE WERE CLR TO CROSS RWY 35C THUS CAUSING THE SCENARIO. THE TWR SUPVR APOLOGIZED AND SAID NO LOSS OF SEPARATION OCCURRED.
