This songs referring to god as an Indian giver as one who gives gifts and wants it back later. The gift for god is life and how it can later be taken away. The asshole is referring to an average person who lives their life and asks too many questions about it and should just live the life they are given because existence is as random as nonexistence and if you worry about it your whole life you wont live the actual one you have been given. Also how sad some people's lives are in that they try to make such meaning out of it when no meaning was given to it in the first place. Some are so scared to take chances and put themselves out there and living for something else that is greater than themselves that they forget they're alive themselves. "Get on your horse and ride" meaning to just live your own life to the fullest extent you can live it.
