pinky dinky is a small penis or "dinky" as some girls will call it, usually the girl will look at her own pinky finger or her thumb and she will laugh if your dick is the same size or smaller
Tiffanie looked down and saw that his dick was even smaller than her thumb. She almost choked with laughter but tried to remain calm. She quickly realized her thumb was bigger than Travis' pinky dinky. She started to laugh, but needed a ride home so she caught herself. The following week, every girl in high school would not date Travis unless they were interested in small penises.
