Thanks for the replies.

The experience last night that set this guy off was similar to the ones posted. I was one of two callers. He was in the BB. He was upset because I called his bets (each one equal to the BB) to the river and beat him with a pair of aces, to his pair of kings.

It was late in a MTT and I had a stack much bigger than his to begin with. Winning that hand pretty much elminated him.

What gets me is these guys who get behind a keyboard and all of a sudden they're Rambo.
