Step-Sister Syndrome

A girl who is very attractive but due to more attractive sister(s) or long term friends has not gotten exposed to people thinking she's hot since they all go for the sister or friend. Usually consider themselves ugly and like in Ugly Duckling Syndrome have good personalities and will date any guy because "Looks aren't important" and they have a good sense of humor.

Originates from Cinderella.

Aaron: Amy you're hot
Amy: No I'm not, my sisters are and I got the shitty genes
Aaron: Want to come over later?
Amy: Sure, your funny.
Aaron: Hurray for Step-Sister Syndrome

sister

Female sibling. A sister is a childhood best friend, lifetime protector, you’re rock and the mother of you’re nephews/nieces. A sister knows all of you’re flaws and loves you just the same. She also knows all of you’re strengths. No one keeps secrets like a sister and that is something very special. While you always have parents, not everyone has a sister. That makes them all the more special. Often many called their sisters “sissy” into adulthood or just referred to as “sis”

My sister loves me very much.
