Cubular describes anything which is "cool" in a "business-geek" office-context. Often used ironically. This is a term derived from "cubicle" and the surf-slang "tubular."
The latest Blackberry; a new flat-panel display; highly effective CRM software; an entertaining web site; the latest designer cubicle-space or office furniture: all these things are "cubular."
