Pickup names are almost always misleading, because they're largely created by marketing weenies who have a different agenda: they're charged with selling the little rascals to hero worshippers, not using them to create music. Unfortunately, as has been pointed out in the past (Martin Mull is often given credit), talking about tone is like dancing about architecture. There's no common ground. It's a complete and total disconnect. So, what adjectives do you use? You almost have no choice but to appeal to emotion, where again words fail. But, at least you can paint a word picture, so you describe anger, destruction, happiness, serenity, darkness, complacency, light, control, etc. in terms that don't use those heavily loaded words and hope it strikes a chord (no pun intended).
What's worse is even if they could describe how something sounds, there's no guarantee or even any modicum of assurance that the behavior they describe is what you'll experience once those pickups are installed in your particular guitar. The strings, the neck, the bridge, the cord, the special effects, the amp, the speakers, the microphones, etc., etc., and most importantly, your playing style all have their contribution to make, so all bets are off.
I agonize every time I buy pickups because I have very little idea how something is going to sound once it's built. Sometimes, I'm pleased. Other times, not so much. But, on the plus side, it's always fun. And the great thing about electrics is the majority of the instrument's character comes from the pickups, so you can always change it easily. As long as the thing plays well, tone is fungible.
