term used when many monsters are chasing a player who is trying to run away

A flock of angry mobs chasing some poor character to the zone border. The group of monsters picks up others along the way until an entire line of them is chasing the poor sap.

Some zones in the game are so frequented by trains that most of the mobs are permanently at the border making the depths of the dungeons often the safest places to be for some peace and quiet.
