I don't know about you. But it seems that whenever I am online, there is someone that get's easily pissed of. So why not just troll them so they can get even more pissed? That's exactly how I spend most of my time on Xbox live. So if you are a potential multiplayer troll, then I got a few tips.
1: If you're a male. Go around lobbies saying I love you to people. The result are a bunch of people getting pissed of and calling you gay and the f word.
2: If a squeaker is in sight, call them out on it. And make a funny joke about it.
3: Pretend you're arguing with your parents.
