Once a woman sleeps with a black man, no white man will be able to satisfy her, so she sleeps only with black men from then on. Usually because of their girth and size, but also because they appreciate more types of women in general and have better moves.
After she'd been with two black guys, she realized that once you go black, you never go back, because size really does matter.

Girl 2: But "once you go black, your never going back!"

The full lips and the perfectly rythmic grind
The sexy voice and unfaltering self-assurance.
