You know what context I mean -- calling people trolls in response to a dumb, off-topic, negative, or oppositional comment.  In this case, "correct" context is a matter of subjectivity, and in my opinion, this context is reserved for hideous gnome-like creatures living under bridges.  It's a bandwagon word, it shows no originality or thought, it makes the person who says it look equally stupid, it's too frequently used (especially towards those who support bitcoin but happen to have legitimate concerns about it's current state or future), and it's simply unappealing.  Imagine being a newcomer to a town where everyone is running around calling each other 'trolls.'  It makes the community look extremely weird and I'll bet that it does nothing to encourage new Bitcoin users to become part of it.
