And we was raging I'm gauging a shotty
Tyler is obviously raging as he kills these people/fights the task force, the line “gauging a shotty” makes no literal sense as a “gauge” on a weapon is the measure of its bores diameter. The word, therefore, is most likely included purely for the purpose of rhyme, as well as to add to the feel of a shotgun as a 12-gauge shotgun is one of the most commonly referred. Tyler probably means that he’s pumping the shotgun.
