E-nic is what I like. PVs have been around before e-cigarettes and used for the other stuff...
While moderately clever, and you don't have to explain how to pronounce it like a previous poster's "BOVD", it won't work.
First of all, it leaves out a huge chunk of PV users that use 0 nicotine. Secondly, it leaves out what I believe to be one of the best aspects of the whole enchilada : vapor. Not only is the word "vapor" a cooler word than most, the playing with the vapor, whether using it as a breathing controlled delivery of nicotine, or as a way of blowing out Smaug sized clouds, "vapor" is the central truth of what is going on. And thirdly, it reminds people of nicotine. Nicotine, for good or ill, and ironically, does not have a glowing reputation.
I don't know even about PV. I mean, sure, you don't want some stranger sucking down on your vape gear, but is it necessary to stress the "personal", isn't that sort of implied when you arrived with it, (the PV) perhaps even holding it? Isn't that like screaming "Mine!"?
Why not try to co-opt a letter of the alphabet to be associated with it for ever?
Why not when someone asks what it is, you reply, " My V, ... My V, my vaporizor.
Or not,
Seems my ideas are equally dumb.
Call it what you want, Shakespeare, the rose, and any other name stuff, ... Out.
