"The Cissy" is the third episode in the eighteenth season of the American animated television series South Park.
While waiting for the school bus, the thoughts of Eric Cartman are heard as he angrily thinks about the bullying he has apparently experienced, and discusses the item in his pocket, implied to be a gun.
Getting tired of the stalls in the boys' room being occupied, he puts a bow on his hat, which was the actual item in his pocket and claims to be "transginger" (a malapropism of transgender) in order to use the girls' toilets at school.
Randy is struggling to keep this secret from both his wife Sharon, and from a suspicious Spin magazine reporter named Brandon Carlile.
After angrily confronting Principal Victoria, Cartman takes his anger out on Wendy's boyfriend Stan by saying dating her makes him gay.
Cartman teases Stan about his gender confusion issues, coining the insult "cissy", based on the term "cisgender".
Enjoying the music, and realizing the deep personal meaning behind it, the female geologists decide to accept Randy's alias, and Brandon Carlile (the Spin magazine reporter) deletes his exposé on Lorde.
Sia confirmed her involvement in an interview with NME in February 2015, and also praised the song written by Trey Parker.
[7] Slate's Christin Scarlett Milloy lauded the episode's approach to transgender issues, noting, "when it comes to trans in mainstream media, it seems the tables have finally begun to turn".
