What does this Italian sentence mean?

I know what the calloni means because I think it's a word from somewhere in Italy like a surname. She said 'siiiiii quanto siamo calloni cazzo ♥'. A guy said 'Calloni x6' or 'Calloni (x6)' to her I think before it and my stuff said that she is saying 'how much we are *****g calloni ♥' or 'how much we are calloni *******. I need a 100% sure person so I will know what she is saying to him
