Some people wouldn't be satisfied that a firearm is being transported in a vehicle in a safe manner until the receiver has been arc welded to the frame rails.
I don't get why the ganstalicious Tahoe was "gay" either. Maybe it came from the factory with a tow hitch that was only compatible with towing other Tahoes. Maybe it was a Tahomosexual.
Actually, if you look closely, the Tahoe is ogling a pickup truck sporting some "truck nutz" just a few spaces forward. Assuming the Tahoe is a male vehicle, of course.
