A blend of crap and propaganda. The term is used to define the rumors, misinformation, and lies which are spread for the purpose of helping or injuring a person or institution... but are such blatant and utter pieces of crap, that the word 'propaganda' alone falls short of being an accurate classification.
WMD's in Iraq is Crapaganda. Osama Bin Ladin and 911 linked to Saddam Hussein is Crapaganda. Niger yellow cake being shipped to Iqaq is Crapaganda.
