I agree with everything that everyone has said, minus the burping part. Haven’t experienced that, ever.
Another thing that pisses the hell out of me is when someone in the row in front of me is acting all “into” the prayer. The entire row would go to sajda after the rukoo but that one person will pause and go slowly. The timing works in a way that when I am about to go put my forehead on the ground, his ass hits me on my head because while I am trying to make sajda, he is bending down with his ass all the way out and BAM!
Normally when I see that this is about to happen, I slow down but if the person doesn’t catch up with the entire row, then what I do is that I bump my head on his ass on purpose and he gets a little push from me. Next time he doesn’t repeat it
