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.

Cisgender (opposite for transgender). People who like the gender they were born with.
Emma: Seriously, all these tumblr users using a bunch of wierd words... Like what is ''cis''?
Veronica: Cis means liking your gender you were born with, I am cis. I was born a girl and I like being a girl.

Short for cisgender. Someone whose gender is the same as the gender they were assigned at birth. Not transgender.
Derek is male and he was assigned male at birth, so he is cis. Tracy was assigned male at birth but she is female, she is not cis.

someone who is not transgender. someone who agrees with the gender they were assigned at birth. not a slur or derogatory word, just a word with a non-offensive definition.
since I was born male and still am a male and do not have plans or wishes to transition, i am cisgender.

oh, not you an ultra libtard dipshit now huh.

no, I literally just think it's an accurate description of my gender identity. fucking get over yourself. not everyone wants to demean you because you exist. also, i would like not to be called a dipshit for using words with definitions please.

I term used by the transgender lobby is describe women who have had femininity pushed down their throat since birth. They claim being oppressed by hierarchical, limiting gender roles is a PRIVILEGE! These term is misogynist because it erases women's lived reality in favour of men ("transwomen").
"Transwoman" wow that cis female is so lucky to be treated like a fuck toy and degraded by men her whole life!
