I don't know. I think art has a reason behind its creation, and that it's not always art for art's sake. What with the alleged humor of both Big Business and the Melvins collaborating on ideas for an album's title and cover art, and with the lowest common denominator in mind when selling music to their fan base (sex and violence), I think the Melvins are capable of a sleight joke. They don't have to be Tool to make something so hilarious.
But, it's just an interpretation. I'm sure it actually, REALLY, means nothing more than, "Hey man, get drunk and/ or stoned while listening to my murderous bong riffs and date raping drum blasts, dude. Let's party and shit!"
