Means to be really cold (think day when there is snow and ice and you are outside for a while). So cold that you are shivering a little. Maybe you are shivering a little more than a little bit. It is not freezing, but you sure are very cold. You are not just a little cold - you are froschyating.
Man, I can't wait until my train comes. I am beyond cold right now. I hope there is heat on that train. I am really froschyating.
