Another nickname for a boy. This boy can be anywhere from 13-20 years old. He is very good looking, smart, popular, atheletic. But aside from being everygirl's dream boy, a Kai is known to be a total bastard. He toys with the hearts of girls in a general 10 mile radius and plays evil mind games with his victims. Known to date Megans and some times even Roxannes. But in the end even the Megans and Roxannes don't win for the Kai moves on to his next prey.
Jamie is a Kai survivor. She is forever haunted by the memory of when he sicced his many blonde lapdogs on her. She will never completely heal.

An amazing sexy person who is who probably is Asian which means that they are good at pretty much everything except for getting fat. Made of 100% muscle. Everybody is jealous of him because of his amazing looks and skills. Even though Kai is asian, he can still pronounce his "r"s and "l"s. If you see him you might as well ask for his autograph or hump him.
Wow i wish if I was as nice as Kai.
