I'd meet up sometime. It's hard to believe that people on the other end are actually real PEOPLE until you see them.
I consider myself "Great" (in the empirial sense) at Tetris Revolution, or any original style competitive Tetris, able to completely destroy the hardest AI in under 2 minutes. I've only been beat once on Live by someone named mrmonstercock. Worst experience ever! The shame! TT_TT
So, should I watch out for dshwshr55?
I don't have xbox live, but I play on my friend's brother's account alllll the time.
This one time, some kid (could be the voice mask, but he sounded like he was 13) was having an argument with some other dude while we were waiting for our match to load and I couldn't stand it anymore so I turned on my mic and shouted "SHUT UP!!!!". They totally went silent 
Ah, well let me know next time you plan on playing.
Me, I get the same thing all the time. I'll be playing Halo, and someone (not always a kid) is really annoying, so I mute them, and then talk about them. This is always funny cos inevitably, someone has their TV turned up loud, and has their incoming communication coming through the tv. Then I can hear the muted offender on someone else's headset (barely) and they're really pissed off at me. I laugh, and taunt them further, and they eventually team kill me, and I boot their annoying self.
As far as my worst, it's when you get one annoying guy who doesn't shut up, but then I'm the only one who uses the mute feature. Everyone else keeps yelling, "Dude, SHUT UP" and eventually, I just take off the headset. Hardly anyone actually communicate anymore.
