Someone who doesn't know how to spell Jillian. :)
Also one of the best, sweetest, cutest girls ever. Amazing to be around and get to know, extremely fun, seriously lovable, constantly denies she's cute but is incredibly adorable.
Very special, although will divorce you multiple times over only to run back to you. Hella slutty, but in a good way. Very hard to offend but easy to piss off.
