Simply Stated:

"Chicas Atractivas" is Spanish for "Sexy Girls".

We wanted the domain name "sexy-girls.com" but uh, we couldn't afford it...

So we thought, Spanish is the most common and most spoken language in the world,
so - eventually, maybe, hopefully, someday Spanish domains names will become more popular.
 
As it is that all the good english ones are either not for sale or way too expensive, I mean who knows right - ??
