= J =
[Usenet: by analogy with spam] A message
that is both excessively cross-posted and too frequently posted, as
opposed to spam (which is merely too frequently posted) or
velveeta (which is merely excessively cross-posted). This term is
widely recognized but not commonly used; most people refer to both
kinds of abuse or their combination as spam.
