The stage 2 boss of Touhou 6: EoSD. The only stage 2 boss to ever get that much screen time. Arguably the strongest in all of Gensokyo.
If one is attacked by Cirno, the best defense is to talk calmly to her, and ask her a riddle. No matter how easy the riddle, there will be enough time to flee while she tries to figure out the answer.

Cirno Day 

⑨ /⑨ /0⑨ , also known as ⑨ day, but more commonly used to refer to the day Cirno became supreme overlord of our planet, solely because she is THE STRONGEST IN ALL OF Gensokyo. CIRNO IS OUR OVERLORD. HAIL CIRNO.

Touhou fan #2: Yeah, ⑨/ ⑨ /10 and ⑨ /⑨ /11 can never compare. Although they're pretty nice, the anniversary of our strongest overlord is quite a ⑨ ish event, you know.
Touhou fan #3: Happy Cirno Day, bakas! *spams danmaku*

endwarfins

The rush of neurotransmitters and neuropeptides triggered specifically by watching the Seven Dwarfs march home singing "Heigh-Ho" — that particular high of pickaxes, whistling while you work, and communal domestic bliss in a cottage built for men half your height.
I only meant to watch the Heigh-Ho scene for the endwarfins, and then it was two hours later and I'd watched the whole movie.

Endwarfins aren't just a Snow White thing — I get the same hit off the Lollipop Guild in Oz.

A slang term used to describe a bald person, typically someone who is completely bald or has a closely shaved head. The term is derived from the infamous, hairless kids’ cartoon character of the same name.
Example 1:
“Did you see that caillou over there? His head is reflecting the sun like a disco ball.”
Example 2:
“I think Dave is finally accepting his hair loss. He just went full caillou and shaved the whole thing off.”
