Wow, she says she likes your little short story, and so you mean to cause offense to her? Well, I'd say that you're certainly a troll, but I think that Nevermind definately outtrolls you in most accounts, and always will untill you work out a better strategy.
Anyway, Zen is basically the belief that wisdom comes through self-enlightenment, rather than theoretical knowledge. This self-enlightenment is normally achieved through meditation on a subject. Although there is a lot more to it than that, when most people say that something is "Zen", they basically mean that it is very well thought out and philosophical.
So yeah, it's not an insult, and treating something like it is an insult is never a good idea if you don't know what it actually is. Trust me, you'll have a much easier time on here if you simply go with the flow. Try asking a few more questions rather than snap in the meantime.
