I call my doggie a 'piggy' all the time, because she is a piggy. But not literally. Not because she looks like a piggy (well, she has a big belly) but because she consumes as much as a pink porker. And because she rolls in mud a lot.
She does not like it because she says that it is just playing on words. She says that she is really a doggie.
My dog is a kitty-pig and he knows it. He looks like a pig and thinks he is a cat. Pugs are weird that way.
But as to topic--Do you know of any newbie that is going to search for "E-NI," "PV" or anything other than "electronic cigarette?"
If you want people to find us or products, they need to be called by what they are.
I'm not ashamed of my collection of electronic cigarettes. I don't smoke them, I do vape them, though, so maybe the devices can remain named e-cigs but we need to get the word out that we do not smoke them.
I think it will just confuse people.
