n: a relatively small separate tank or a small part of a larger tank that holds a small amount of mud for a special purpose. For example, it may hold a small quantity of heavy mud that will be used to slug the drill string. That is, the slug will be pumped into the string to keep mud from falling onto the rig floor when a drill pipe joint is broken out during a trip.
