It's a pun: good bath → ii furo in Japanese.
Ii: 11
Furo: fu (2 in the hifumi numbering system) + ro (short for roku, 6 in the ichinisan numbering system)
Good Follow Day!
Another pun. "Furo" (bath in Japanese) is close enough to the way "follow" is pronounced in Japanese ("foroo"). On the internet, this "follow" is mostly used as in "following in social media".You... You saw it, didn't you...?
