Star Wars sequels directed by Anthony (Katie) Retardo where Anthony (Katie) screams 'THIS, IS FOR JASOOOON!'. During the live stream of these videos on stream in 2016, Gold_Ultima of the same name ('Jason') was present and the stream took it as a hilarious reference to Gold_Ultima.

Creator(s)

Usage
