Transgender women are not accepted into the girls squad. A group of women who won’t hang out with transgender women. A group of heterosexual women is Sis Privilege. Sis privilege is a tight knit group of natural born heterosexual women. A group of women who don’t like transgender women. The party is Sis Priv only.
The girls night out was sis priv only. She wasn’t invited to girls night out because she’s transgender.

Get the sis privmug. The best! A person with 10/10 look, personality, talent, skill, everything! Very intelligent but very childish. A great friend, girlfriend, or companion.

Get the si qinmug. Si-Cilya is a girl that will always be there for you. She is a beauty that attracts all kinds of people. She's smart, kind, forgiving, and a great friend. She always wants to make people happy and constantly tries to make people smile. A genuinely nice girl who should be treated like the beautiful princess she is. She's a good person to be around, so if you ever meet one, never let her go. Ever. She's a social, cunning, passionate woman. To have a Si-Cilya as a friend is to be extremely fortunate. Once you've pissed her off, you shall pay for the rest of your life! However, this somehow does not threaten her people skills. You will most likely fall in love with her because of her grace and kindness. She loves all and loves people for their souls, she will always find good in people. Don't ever underestimate her, she is a very brave one. She is a mixture of lush and sexy. Although she's a really bold and sometimes quirky person, Si-Cilya is usually a perfectionist and she might be really hard on herself in private. She can be stubborn, and won't stop an argument until she has made her point, but she is also forgiving and loyal. She will break your heart even if you didn't even know you loved her in the first place. Her smile, that damn smile will make you feel at home, her eyes are the most gorgeous things you may ever see, her lips are gorgeous, her humor can make you die of laughter.

Get the Si-Cilyamug. When you say a word too much that it becomes it's own word. Saying Analysis while on a marijuana-induced procrastination spree results in the following: Anal Sis. It refers to the act of either giving or receiving anal and then calling up your sister to tell him about it.
