"didee-mao"

I wondered about this as well until I heard one of our
roleplaying/wargaming group use it. It is Vietnamese
and means 'retreat', 'run away', 'bug out'...

Not great books but good fun, especially the third (?)
where Bun-bun the Shiva gun stars. I read the first
two as HTML from a CD that came with an Honour
Harrington book and bought the third - in hardback
becasue I could not wait - and it had another CD...
Baen's cocaineware policy of giving free books on CD works well with me
anyway.
