Meaning of "Grandma Was A Nazi" by Darkbuster

The lyrics of "Grandma Was A Nazi" by Darkbuster seem to convey a sense of indifference towards a grandmother's potential involvement with a controversial and reprehensible ideology like Nazism. The lyrics suggest that despite any past affiliations or beliefs the grandmother may have held, it doesn't matter in the present day, highlighting the passage of time and changing generational attitudes. The casual and dismissive tone towards such a serious topic can be interpreted as a form of dark humor or a commentary on how distant past events can lose their significance over time. The use of the term "Yahtzee!" at the end may serve as a sarcastic or flippant way to further underscore the nonchalance towards the grandmother's past.
