The (partial) "Urban" definition of the term

"A general term for someone who carries out actions with such stupidity that they might as well wear their [derriere] as a hat." Example: "Linden Lab is an asshat for thinking SL could only mean 'Second Life' and nothing else, such as 'Sign Language'"

Since there is no relationship to "Second Life" all you Linden Lab lawyers can kiss my ... well, go to Google with any take-down notices, because I outright refuse.
