"Lazy" usually means that the work is done just when needed, not in advance.

For example, in a lazy loaded cache, on start-up the cache is empty. When a request is made for a particular keyed object from the cache, if it's not in the cache yet, it's retrieved at that time from some slower source, such as a disk or a database. The same idea extends to EJBs and DB replication. I don't know what it means in master/detail relation, probably something similar.
