I used to tell girlfriend that his boyfriend was nothing more than a troll — the definition of which I was made to look up after someone else overheard me saying this. And I told her that when she eventually attacked me she did it again.

I found the definition to be that I mean long, warts, smelled bad, lived underground; we can find such trolls in movies and television.

What I meant was he was using my boyfriend for information and was getting him in trouble luring him away from his responsibilities, and when he was caught, telling the person who caught him that it was my boyfriend’s idea all along.

Is troll abusive? Is it a word? Is it insensitive to call someone a troll?
