In anticipation of next week's release of Crackdown 2, MTV Multiplayer has slapped together "Crackdown 2 Guide to Griefing: How to Make Your Xbox Live Friends Hate You." Of course, you could just continually ask them to join a party while they are trying to watch something important on Netflix like an Akira Kurosawa movie (you know who you are) to accomplish that goal.
The guide features five irritating (from your friends' perspective anyway) activities you can engage in to make people hate you with colorful names like The Alabama Roof Push, The Kalamazoo Car Toss, The Dangling Gift Horse, The Live Orb Snatch 'N Grab, and the The Hangman's Grift. Here's one example:
The Alabama Roof Push
There's a weapon in "Crackdown 2" called the UV Shotgun which unlocks at Guns Level 2. This should be the griefer's best friend. The gun's true purpose is to kill the mutant-like freaks en masse, but shooting non-freaks makes the gun act like a non-lethal force push, sending the target flying 30 feet in the opposite direction. I think you see where I'm going with this.
The Situation: You and a friend spend 10 minutes climbing up a building to get the 4X agility orb on the roof. Because you're better than he is, you make it to the top first.
The Grief: Just as he makes the final jump to get up to the roof, you shoot him in the face with the UV Shotgun.
The Payoff: He goes flying and probably dies from the fall. Fantastic.
You can read them all at MTV Multiplayer. Griefing can be fun as long as you and your friends are both engaged in the activity, so if you are going to try some of these tricks you'd best make sure the people you invite into your games aren't thin-skinned crybabies.
