Bonus Sister

Same relation as a stepsister, but with positive connotations as opposed to the negativity that is typically associated with a Stepfamily. Bonus family members are chosen freely and they enrich your life.

My mother remarried after I moved out of the house. I am a good friend with her new husband. As an added bonus, I was introduced to an awesome new awesome friend: my Bonus Sister.

Hilton Sisters

Like the Olsen Twins, but with even more crack, and even less credentials.

sister complex

Excessive love for one's sister(s), often past the point of ordinary brother-sister/sister-sister relation. Often used as a tease/insult for a person who's overly protective of his/her sister, and is shortened as sis con or sis-con.


Derived from Japanese word "shisukon" (sis con), and is often used in manga and light novels.

M: Ota has a sister complex.
O: like hell I have!
M: Please, you've got your sister's picture posted all over your room, your facebook profile picture (and several hundred picture) are you and your sister, and you get pissed whenever we talk about your sister.
