hmmmm... I only read this thread to convince myself that it was really happening.
I am not a child (unless you mean 'child of the 1960s'), and I use the term 'vape' (sometimes 'vapestick') to refer to my mechanical 'mod'. As we are still in the early stages of this huge shift in the way people choose to internalise their nicotine, 'vape' seems to be the only term that you do not have to constantly explain to the uninitiated. I never, ever, ever use the term 'mod' (except in a context such as this) as it does not mean anything to anybody. Electronic Cigarette is too long-winded. My wife calls it my 'pipe'.
What's more, the amount of bile that is generated against people choosing to refer to their own things in a way that makes sense to them is pointless, petty and puerile.
It reminds me of a post a while back where people were laughing at the 'idiots' who chose to position their drip tips in the centre of their mouths, as opposed to the side. (No, I'm serious, that really upset someone too, apparently).
People talk about a vaping 'community' as though it is some coherent group of people who all think and act in the same way. This is not the case, but posts like this make me wish that it was.
Incidentally, the term 'vape' might be used as a verb, and is a convenient verb for the purpose. But of course, it probably originated from the noun vapour (vapor if you are from the US).
Finally, if those 'kids' who choose to call their electronic cigarettes 'vapes' are not killing themselves by smoking tobacco, then I would like to congratulate them on a wise lifestyle choice. I have no desire to belittle them for their use of language, or to wish any toy related injuries to befall them.
