She says she doesn't see it, but I think people that don't even know her can see it from a mile away. She has a great smile that can make your day, and she seems to always have a smile to spare. She is very nice and caring and doesn't judge you. She is very cute and has a lot of little things that she does that can make you smile or laugh. She is very smart and always knows the right things to say. She is fun to hang out with and talk to. She is a very amazing person for so many reasons. She says she doesn't see it, but she should. She is a good singer too. Si-Si is perfect in every way and I am so glad that I get to call her my friend.
What song is this Si-Si?

A best friend that you can call sis-sis instead of sis. Female version of brobro. Guys can have a best friend that is a girl that you can call sis-sis and nothing is going on or no one is going out.. Normally if you are best friends you can treat her like a real sister. You can love her like a real sister say I love you like you say to a real sister. Basically best friends.
Jason: Wow Chelsea, we have been friends for years now and I proud to call you my sis-sis.

Chelsea: Thanks Jason! Can I call you brobro?

Jason: Sure sis-sis.

Chelsea: Love ya brobro.

Jason: Love ya sis-sis.

Short for the word “sister” but also just an answer to any question ever.

Janet: “sis...”
Susan: “omg sis what’s the tea sis—spill!”
Janet: “sis!”
