An online discussion thread that gets out of control. It often splits into conflict and an off-topic discussion. Like a train wreck, it 'moves quickly' because people are posting faster than they are reading the responses.
That Yahoo news forum on Dubya is such a train wreck. People are yelling and talking about terrorists. I can't keep up with it.
