Cisgender

A very gay way of saying heterosexual. Considered derogatory to any sane person.
Heterophobia.

That transgender keeps calling me a cisgender instead of heterosexual and I'm considering filing a lawsuit for disrespecting my pronouns.

Cisgend

A proper, if derogatory way to refer to a hateful person who identifies with their biological gender, in other words, TRASH!

My Friend: So that went well...
Me: It's a stretch to say that went well, that damn Cisgend ran amok over me using the bathroom of the gender I identify with. But whatever she was trash, so I'll be fine, might have almost got into a knock down drag out maybe teared up a bit, but I'm fine.
