What does the term "grab, squeeze, and pull" mean in women's self defense?

I was taught in my self defense class to grab the testicles, squeeze as hard and as long as you can while pulling down, to cause additional pain and incapacitation to your attacker.

It's called a no-fail defense against rape.

What is the best martial art for self defense for women and kids?

My young children and I would like to learn a martial art/ self defense. What is the best martial art for this? If there are no classes in my area, does anyone know any step-by-step instructions on line somewhere? We just need to learn how to get out of a bad situation fast if we have to. Thanks.
Thank you everyone for your responses!

Wing Chun is a Chinese martial art system that was actually invented by a woman (Shaolin nun Ng Mei). It is predominantly a self defence art, is easy to learn the basics, doesn't rely on size or brute strength. It is based around natural body movements and embraces ideas like economy of movement and redirecting force to make it effective. Google Wing Chun in your country for a list of reputable schools. Good Luck
