it's short hand for big bang 🫡🫡 (as in the enstars big bang) i used to call recital my bb fic (and i still do, just not as much) bc we weren't allowed to say much about our pieces during the creation period and the playlist i made to go along w it is the bb playlist. also i have a tendency to call my fics by their 'working titles' aka what i call it while i'm writing it like forehead kiss fic (close to you), meowzart debut (trio), height difference sillies (five centimeters)
