Once you've experienced the soft brown skin and muscular arms
The full lips and the perfectly rythmic grind
The sexy voice and unfaltering self-assurance.
You can never go back to what you might have known before.

Once you go black, you'll never go back
Lisa: I have kissed the most handsome guy last night, I felt so protected in his arms.

Rachel: What did he look like?

Lisa: He was strong and dark and so handsome

Rachel: Oh Dear! You do know that once you go black, you'll never go back?!

This statement derives from the general relativity theory published by Albert Einstein in 1915. It refers about the event in which an accelerated body crosses the spacetime boundary of a black hole known as the "event horizon". Beyond this boundary or "point of no return" the gravitational pull becomes so great as to make escape impossible and thus "you'll never go back".
"If a black hole is an oyster then the singularity is the pearl inside. The gravity is so strong it’s always hidden in darkness, beyond the horizon. That’s why we call it a black hole, once you go black you'll never go back."

Just like 1 being larger than 2, "once you go black you'll never go back" is false.
