Phrase used to describe someone of extremely low intelligence. A Bushtard is far more dense than a retard and has an IQ closer to that of George W. Bush.
A portmanteau of the words bastard, retard and the name of the current President of the United States of America, George W. Bush. Used to refer to supporters of his policy, ignorant statements supporting them, as well as the man himself.
A particularly bad type of spyware that makes secret copies of everything on your hard drive, fries that same hard drive, and sells it to the highest bidder - including terrorist groups and countries known to support terrorism. If this type of spyware is discovered, it fights all attempts to remove it by repeating the words "national security" or getting Bill O'Rielly to attack those trying to remove Bushware from infected computers. Software that behaves exactly as George W. Bush does.
