Get the sismug. an incredibly annoying yet popular term used mainly by teenage girls. “sis” or “sister” originated from the popular yet toxic youtuber james charles. the word usually replaces someone’s name in a phrase, and it not meant to be offensive for the most part. can be used rudely though, as seen in example 2. word for the wise, try to keep the number of times you use this word a day to 0.

Get the sismug. A sis is a bump which women may get on their breast which is just a build up of fluid but often thought to be a cancerous bump.
My aunti went to the doctors yesturday to see about that bump on her lower breast but it wasnt cancer, it was a sis thank God.

Get the sismug. 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.
