to have the "ballsy nerve".
That depends on whether you actually mean 'whine' or if you have a typo for 'wine'. You might say something like 'I don't know how she has the gall to whine' meaning that you are surprised someone has the effrontery to complain. On the other hand gall is a bitter substance, and 'wine mixed with gall' was offered to Christ when He was dying on the cross. Why the wine was mixed with gall is a matter for debate, as people have different theories about exactly what it was, but adding gall to wine makes it bitter.

Light-coloured poo poo's! Pale feces can mean you have gall stones blocking what is called the common bile duct leading from your gall bladder to your liver. The bile that is collected in your gall bladder is secreted in to the liver which is then secreted into the stomach to help digest fats that you have eaten. This bile is the substance that turns your feces to a brownish color, so if your feces is pale colored, you most likely have a blockage of your gall bladder.
