I looked around and didn't see anyone posting this, so if it's a repost sorry.
This is meant to be used if you are running away from a mob, such as to save your life and what not. This is fairly simple as it only requires you to spam two keys on the keyboard while running. If you have the default Q and E keys that are strafe this should work. From what I've heard mobs follow you until a number of footsteps has been made. All you have to do is while running spam Q and E, until the mob turns around and runs back. Seems kind of simple but it works, I do it all the time, you can even turn around and look at the mob, and most of the time he'll be glitching left and right as well, the mob also leaves earlier than if I were to run in a straight line to get away from it.
