So in pixiv (one of the biggest artist communities in japanese internet) they always celebrate the pairing the 10 of October. There's also a Zangoose day, and more shit like that.
It's a japanese thing to relate things by common "syllables" due to how their language works (with characters). Pic related as an example of this little trope appearing like something so trivial.
