A term that is given to girls when they are hanging out with one or more girls who are similar looking and are, friendly, sweet and drop dead gorgeous. It is a term only given to girls whom you have the urge to fall in love with. Basically it is a term generally used to describe your favorite sisters. (But they've got to be hott)
AH! I'm going to have to diagnose Hannah and Caroline with Hulseyastic syndrome because they are the best sisters that i have ever known. They are filled with intelligence, kindness, and sweetness on the inside, and they are as beautifull on the outside as they are on the inside.
