Reminds of the clip where they're doing Twitter Space in Reine's bath and Reine said to Ollie: "Do you know what's Yukadon, Ollie?"
Ollie: "no, what's that?"
Reine: "It's like Kabedon but on the floor"
Ollie: lay down immediately
Towa: "So.... yeah, we really got drunk last night and our "magic" intertwined...... kinda"
Kanata: "I don't know how it happened, just when we woke up, we already in the bed, naked"
I think there's an IRL story on Facebook I saw: There's a guy who bought 2 dakimakuras and he put those 2 dakimakura on his bed so they can be a couple and the guy sleep on the floor.
