A google of the term doesn't really bring up anything I understand. It seems to be some technical computing term. This link is really only interesting because of the last name of the author is the same as our red round protagonist.
Is it a DUmmy code for Internet Messaging? I ask because in my googling it isn't capitalized like in the above DUmmie post I linked.
Other then things about graphical user interfaces, I only find reference in the British press about Palestinians using iconic manipulation by equating the swastika to the Star of David as in this link which appears to be a message board. Here I quote from it:
In a cruel use of iconic manipulation, Palestinians and the many radical groups who support them post the swastika next to The Star of David equating them. In a column earlier this year in The Los Angeles Times, Walter Reich, the former Director of the U.S. Holocaust Museum pointed out, " ... if the public could be convinced that Israel is no better than Nazi Germany, then the anti-Semites could again be back in business."
Well, I recognized "iconic manipulation" as it is used in symbols and all that--such as those exquisitely hand-painted icons of George Bush, Sr., that one sees in Orthodox Churches in the former Soviet Union (yes, believe it or not, while the rest of the world seems to have forgotten the first George Bush, he is still revered as a near-saint in eastern Europe).
Such contemporary icons are usually placed right next to an icon of a famous saint of the locality, or St. Michael the Archangel (the warrior of God, at least in my Catholic upbringing), or the patron saint of the country.
But as for computer uses, I have no idea; this seems like something the dirty one would engage in?
Given the context, it sounds like some kind of Wiccan voodoo thing.
