People who identify as the gender they were born with. The opposite of transgender. There are idiots in the world who believe cis is a made up word because they clearly don't know the small technology device they use to spread their ignorance, can actually be used to gain simple knowledge....

The terms “cis” and “trans” are from Latin, in which cis means "on this side"2 and trans means "on the other side" or "across". The term "geometric isomerism" is considered an obsolete synonym of "cis/trans isomerism"
I was born with a vagina and identify as a lesbian (I.e A homosexual WOMAN) so I'm cisgendered and so is my sister, also born with a vagina and identities as a woman, who is married to cisgendered Bob(who was born with a penis, and feels like a man) who has 2 brothers, a very feminine homosexual cisgender(born with a penis, wears heels sometimes but feels like a better man because of it) brother, Joe, the other brother Jack is homosexual transgender (born with a vagina, feels like a man (possibly do gender reassignment) and dates both cis- and trans-gender men). I have no idea why people think cisgendered is a hate word or made by unicorns but it's just an better term to use when talking to people who are trying understand when describing a difference between the two.
