Cam someone PLEASE explain this to me..

I am getting sick to the high teeth of this. You play for hours, get a good stack and then this happens.

The worst thing is this lunatic was in 3rd place and I was in 10th..

I can take a beat, but this is just too hard to swallow. OK maybe I shouldnt have shoved after the flop, but what was this idiot doing calling a 5k raise with J 8 ?
