Not to worry - I know the Marines tend to spell it "Uurah!" - and it seems to vary everywhere else it's used... No offense here - it all means the same thing, y'ask me...
I actually just went with a theme from a previous message board where my username was fubar cj, since I've been wheeling a thrashed CJ for the last thirteen years. When I decided to build up the XJ, it wasn't fubar (still looks pretty damn good now) but it fit the theme.
Ther is still plenty of time for fubaronics to manifest themselves upon the XJ....
