For main page, see Thread Derailment.
Thread Derailments occur when a thread is steered away from the topic discussed in the original post to a different topic completely. In ye olde Ponychan, Spiderman could derail a thread in ten seconds flat, but lately, this has changed. It takes much more than one Spiderman macro to completely derail the thread.
