Shadowrun Tabletop has a long history of coming up with acronyms for the core rulebook, from the BBB (Big Blue Book/Big Black Book) to the acronym BABY which was used for the limited editions (I remember it standing for Big All Black Yearbook, but I've seen other old timers say that it was the Black And Blue Yearbook. Like Fastjack, our memories might not be what they once were.)
However SR5's Limited Edition presents a new challenge. It's red. The old acronyms won't fit. So my suggestion is Big Excellent All Red Dragonscale Yearbook.
