Cis 

A senseless slur transactivists use to describe people who are not trans. It also implies that someone identifies with their gender assigned at birth. This is just not the case for most women in the world. We don't identify with our oppression, so just stop forcing labels on us.

CIS 

Acronym for Character Induced Stupidity. Commonly used in comics or anime/manga when the writer injects ridiculously stupid mistakes that may well be against the established canon of a character's history for the sake of advancing the story.

Ash Ketchum constantly receives CIS by releasing his strongest Pokemons every season and lose to the Pokemon League again and again and again.
