I found this site http://lakstyleblog.com/  that has an encyclopedia of K-girls.  It's an LA/OC-based blog but I've recognized some who've made it down to San Diego.  It's useful if you're trying to research girls who have different names or don't have any San Diego reviews yet.

I noticed a lot of pics are Asian?  But Urban Dictionary gave definition of "best girl ever?"  What is it?

From my understanding, a "K-Girl" is a "Korean Girl."

A K-girl is a korean girl..the ones that work in LA, OC and SD are generally all very well trained, ages 21-29, hot as hell. the training leads them all to have a great routine..shower rub down, bbbj in shower..dry you off..massage that turns sexy...kissing your body...most will do rimming if you like...then some very goof fucking...
these girls are mostly angles from heaven

thanks for the website. In the past year I've meet a few K-girls and I'm amazed at the quality.
