A phrase used to describe rampage or spree of destruction. Referencing the famous "Killdozer Rampage" in which Marvin Heemeyer destroyed much of the town of Granby, Colorado on June 4th 2004 using his heavily modified bull dozer.
Dude, if the DMV doesn't stop fucking me around, I swear to god I'm going to end up pulling a granby.
