What is "geekfest"

n. (context informal English) An event or situation that is very geeky.

Geekfest is the name of a series of free, all-ages concerts organized by California indie label S.P.A.M. Records during the 1990s. The first Geekfest was held in June 1996 on the shoreline at Point Molate in Richmond, California. This site, a former Navy fuel depot at the foot of the Richmond-San Rafael Bridge, became the default location for dozens of Geekfests, though other locations were eventually used.
