dapper 

A reference to Dapper Drake, version 6.06 of Ubuntu Linux, slated for release on June 1st 2006.

Dapper Drake was originally meant to compete with Microsoft Windows Vista, but Vista was postponed by a year, because Microsoft is trying to put out an OS that doesn't suck quite as much (it still will though, majorly).
