In the first Expanse book, Leviathan Wakes, there is a scene where a detective is looking through space port logs.

There’s one ship called The Badass Motherfucker. It’s owned by the MYOFB Corporation (presumably, “Mind Your Own Fucking Business”).

They don’t elaborate. The detective passes over it and eventually finds the ship he is after. This particular ship and corp never comes up again.

I feel like we need a spinoff covering whatever the hell these guys are up to, lol.
