I use Touhou references when I make passwords. The most recent one was Superhuman " Hijiri Byakuren" .
I also use a lot of Touhou references in speech,
such as "Calculus of All Humankind", "It's the Dorm Staff conspiracy.", or "People like them should be run over by a train".
But my friends would never know because I say it in a casual way, and they think the train is a reference from the movie Inception
