I agree to that. Besides, what is more satisfying than an opponent freaking  out when you find that one winning move? ;)

Not nescessarily. Usually they send two constables in case of problems at the scene.

So the guy tells the cops, "don't you understand, I'm playing a ten minute game and you are going to make me lose if you ask me a bunch of questions!!!"    So the cops try to take the mouse and other computer controls away from him and he becomes even more agitated...

But the lawyer gets him off in court because a sympathetic jury member is also an avid chess player and chess.com member!  Prosecution wonders why they allowed that chess nut on the jury!

I often do this myself when I'm playing blitz. As you get stronger and play stronger players, you can actually tell their posture by the moves they play and the speed at which they play them. I've had countless games where I could tell my opponent thought very little of my chess skill just by the flow and demeaner of his/her play. So when I'd get a sudden winning advantage like a force piece loss or chechkmating net, I'd yell at the screen: "YEAH! How do you like that? How do you like that S--T?! You're mine, a--hole!" There'd be this long pause and then either they would disconnect or start tossing the rest of their pieces away for nothing.

I especially love doing that when players would open with garbage moves and then suddenly play real strong, basically stating to me: "I think so little of you, I can play Nh3-Na3 and still whip your ass like nothing".

This speaks to a "race to the bottom" not the higher mind, real cognitive thinking that we should be aiming for. 

Hardly. It's like in any sport where you pump your fist and yell triumphantly. That's all it is.

 You're trying to read too much into something that doesn't matter in the first place.

this is BUUUUUULLLLLSH###########TTTTTTTTTTTTTT

Now, now, kids. Behave.

A good friend from across the hall from my dorm room would often do this when he played Modern Warfare online.  Despite not having a headset or microphone to communicate with anyone else involved in the game, he would yell "YOU MOTHERFiretrUCKER," "WHAT A CelerybUNT," and the likes.  At 2 AM.  I remember hearing him clearly even from my own room.

He eventually got in pretty big trouble.  Apparently, swearing is a fineable offense on college campus, being a Christian university and all.  It also violated some curfew/quiet hours thing.  Sadly, there was no police interference, though it certainly would have been more appropriate since the sound effects from the video game could have suggested that someone was armed and dangerous.

EDIT: "Celerybunt" is a baseball term referring to a bunt performed using a large stick of celery in place of a regular baseball bat.  It's not legal within the official rules of baseball, but happens all the time in the famous baseball variant, "Vegetable Baseball" (or "Vegeball" for short).  One of the defining features of the game is that they use potatoes in place of regular baseballs.  Perhaps someone more experienced in the field can elaborate on this.

Playing baseball with food? I'm slowly beginning to understand why they like burning american flags in third world countries...
