I've trolled a guy in a blog once, he was really pissing me of, in fact, it was really funny e.e And I've trolled about other 2 guys e.e I also troll alot on Omegle, when they say hey, I say: こんにちは あなた motherfucker elizabeth shit. Doesn't makes sense, but they get away xD And no, I never bullied somebody.
I troll on Omegle a lot but that doesn't really count.
As for bullying........Eh, sometimes. I sometimes (*coughcoughalotofthetimecough*) threaten または hit them または am just flat-out mean to people, but most of the time I have good reason, like if they're one of those stupid people who acts mean and thinks they're better than everyone else.
i have never trolled has i recall but one time some one pissed me off so much i picked on them for about a week then just left them alone it happed like 2 または 3 years 前 though im diffrent now i refuse to bullie
