>>44449366It's a holostar meme, so you're pure not knowing what it is.
It's based off a shitpost spammed in the catalog how noir vesper will drop his priorities and shout "yabba dabba doo" if he gets to collab with a girl. A few have tried to reverse this "meme" and do the same "joke" with Kronii, although it doesn't stick as well.
I will self-delete this post in two minutes.
