Top Definition
Short for "cisgender" (opposite of "transgender"), used to describe someone whose gender identity matches their anatomical gender at birth.

Occasionally used derogatorily.
Mark: I heard that Stacy decided to start her transition.

David: Huh? Dude, Stacy is cis. You mean her sister.

Short for cis-gendered, meaning someone who identifies with the sex they were born as. Typically used by whiny tumblr users who complain about not being accepted for who they are and yet bash these "cis" people for being born and being okay with the sex they were born with.
I am a female to male transgender and I hate white straight cis men.

Commonwealth of Independent States; putative successor to the USSR, except that the Baltic Republics of Estonia, Latvia, and Lithuania never joined. Contrary to another definition of CIS at the Urban Dictionary, the CIS does not stand for "Communist Independent States." Moreover, that definition has the CIS existing BEFORE 1991, and includes Kazakhstan as "not officially part of the Soviet Union." Kazakhstan was, in fact, one of the 15 republics of the USSR until 1991.

The CIS came into being December 1991. Mostly consists of regularly scheduled conferences of foreign ministers and defense ministers.

In 1995, members Belarus and Russia created the Commonwealth of Sovereign Republics (CSR).
The August 2008 war between Georgia and Russia was unique in being a direct war between CIS member states, although there have been others waged by proxy.

Abbreviation for the Confederacy of Independant Systems. Second worst faction in the Star Wars universe beaten only by the wretched Alliance to Restore the Republic/New Republic as THE worst.
Seperatist movement! Ha! The seperatists are just a bunch of disgruntled corporate moguls who don't want their businesses infringed upon.

Because calling someone who doesn't have gender dysphoria normal is oppressive and implies that just because you're born with a penis or a vagina you're a man or a woman.
Die cis scum.
