The term derives from the salutation "Hyvä veli!", or "Dear brother!", traditionally used to open a letter to a not quite intimate friend. The implication is that since the elites of all fields are drawn from a fairly small pool of people who are mostly more or less acquainted with each other, they can and often do manage public and private affairs amongst themselves, off the record, and outside public scrutiny as they like. As the word "brother" implies, the network is usually presumed to be consisting of males, and thus the term is also sometimes used to refer to the marginalization of women and their exclusion from high positions in both the public and private spheres. There is an equivalent term, "hyvä sisko" ("dear sister"), used in reference to informal networks of women in high positions.
