Cisgender (often abbreviated to simply cis) is a term for people whose experiences of their own gender agree with the sex they were assigned at birth. Cisgender may also be defined as those who have "a gender identity or perform a gender role society considers appropriate for one's sex."

Cisgender ( abbreviated to cis)

an unnecessary and sometimes derogatory term that is synonymous with normal and used to label people who do not deviate from gender norms. Such as females who identify as female and males who identify as male.

Essentially the opposite of transgender; whereas transgender people are those whose gender and assigned sex at birth don't match up, cisgender people are those whose gender and assigned sex at birth are the same.

This definition really shouldn't be hard to understand if you've got a vague grasp of what the word transgender means, but despite this, some cisgender people are under the impression that it's a slur; explaining to these people that it's about as much of a slur as the word heterosexual doesn't do anything to change their mind on this subject, so you can just safely dismiss these people as not very bright.
Jane is a cisgender woman; she was assigned female at birth, and identifies as female.

Sarah is a transgender woman; she was assigned male at birth, but identifies as female.

Bob is a cisgender man; he was assigned male at birth, and identifies as male. He objects to being called cisgender, stating: "I don't like that some tumblr tranny made up a term to describe me, it's insulting! I'm just normal!" He does not see the irony in objecting to cisgender but being perfectly a-ok with tranny, an actual slur.

Not a derogatory term at all as many transgender people use it to describe people they know and sometimes love.
Cisgender is a term for someone who has a gender identity that aligns with what they were assigned at birth. The term was created for referring to "non-transgender" people without alienating transgender people. Basically if you were born a woman and do womanly things and like to be referred to as a woman, then you are a cisgender. Not a bad thing.
I don’t feel my gender in my bones the way some people do—the way my wife, who’s a cisgender lesbian, describes feeling about her femaleness.
