spiffy
     
        /spi'fee/ 1. Said of programs having a pretty, clever, or
        exceptionally well-designed interface. "Have you seen the
        spiffy {X} version of {empire} yet?"  This was common
        mainstream slang during the 1940s.
     
        2. Said sarcastically of a program that is perceived to have
        little more than a flashy interface going for it.  Which
        meaning should be drawn depends delicately on tone of voice
        and context.
