Kind of unrelated, but I know a noob vaper. He's a nice guy, but he also calls eliquid "oil" on a daily basis.
"Dude, I need some more of that oil!"
"Bro, I tried that oil and I just couldn't stand the smell of it!" (It was a tobacco, this guy isn't even a smoker/never was)
My ladyfriend also calls ECF "NCF" or "NFC" almost daily.
I've also heard "smoking your iron <insert ecf-restricted phallic object here>"
