con n.
[from SF fandom] A science-fiction convention.
Not used of other sorts of conventions, such as professional
meetings. This term, unlike many others imported from SF-fan
slang, is widely recognized even by hackers who aren't
fans. "We'd been corresponding on the net for months, then we
met face-to-face at a con."
