A bitch nugget is someone who has a giant zit on their face and hates cats or dogs and is usually an East Asian man. It comes from the word bitch meaning gross and nugget meaning sliced fried potatoes peices, which can also look like a zit on an east asian person. The dog part comes from how both cats and dogs love eating nuggets.
