A derogatory play on words equating liberals to being goofballs, ‘goof’ short for ‘goofy’ … ‘nads’ short for “gonads.” So, you are suppose to draw the conclusion that a ‘goofnad’ is a ‘goofy nut’ liberal.
A goofnad is coming up the street! Wait, I thinkthat person could be a moonbat...no, I was right! That person is a goofnad.
1. Similar to a bandwagon, a goofwagon is a person who's goofiness is so powerful that it infects anyone surrounding them. They will slowly amass followers of their goofiness until the person leaves or the drugs wear off. One should be careful when following a Goofwagon. They tend to have only silly intentions in mind.
