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]
