I'm not sure what pork balls are, other than pork rolled in balls, kindof like hot dogs are pork rolled in tubes. Mini pork balls are just like pork balls, but smaller.
The Pink Mini Pork Ball Lady wears all pink and pigtails, though she must be past thirty. She drives around the city to grill mini pork balls in the back of her pink van. When I see her I feel both sorry for and jealous of her, stuck in her haven of meat and cuteness.
