dirtball n.
[XEROX PARC] A small, perhaps struggling outsider; not in the
major or even the minor leagues. For example, "Xerox is not a
dirtball company".
[Outsiders often observe in the PARC culture an institutional
arrogance which usage of this term exemplifies. The brilliance
and scope of PARC's contributions to computer science have been
such that this superior attitude is not much resented. --ESR]
