How to confuse people using Xbox Live

First of all, make sure you're playing Rock band and have a microphone. Otherwise, people won't be able to hear you and that will be no fun. If your band mates also have microphones, it will be even more fun, as you can hear their reactions.

Now, start searching for band members using Xbox live. Ask them if they have a microphone, speaking in some strange accent and pronouncing words entirely wrong. Then, start your game.

Pick a song that is really hard and then start it (make sure you'll be able to play it first, though). Sometimes, these songs are only avaiable in hard or expert mode, so if your band members are on medium level they will be utterly sad. Desperately, they will try to pick the medium level, but it just won't happen. As the poor guy tries to do this, you just continue talking nonsense in your strange accent.

If your band members happen to be nerds and awesome at guitar hero, pick a song that is impossible to sing - maybe one with only growling all the way through. Then, as the song starts and you "notice" that you don't know it, start screaming of horror and make random sounds to express your fright of the evil song.

Make sure you lose a lot of fans this way, and blame it on your new band members, saying that they are destroying your game. Also, as you're picking the next song, make random announcements such as "WAAH THAT HURTS". They will most likely leave you at this point.

Good job! You have now annoyed and confused someone using Xbox live!
