Well, if you want a more technical explanation of the Butt Out, you can find it here:

If you want an explanation of why it beats Boss Hog, then you have to understand that Boss Hog has commonly been depicted as not only a villain, but as a beast as well. He's always hunting for the Duke boys, but they have managed to turn the hunt around to make Boss Hog the prey and, in the end, are able to take him down. As a hunter, once you have defeated your prey, there are certain actions you must take to insure the kill was not in vain. The Butt Out is one of the simplest, if not most unsettling, ways of doing so. A Hole Hawg, while having an amusing name that is similar to Boss Hog, is merely a common contractor's tool and does not necessarily beat a device that would conceivably be jammed into Boss Hog's anus. And it does follow since Boss Hog wanted your balls, we wanted to have his anus.
Of course, I was just messing with you, since you're apparently the self-appointed moderator of BTP and have decided that if you don't get it, it doesn't beat the picture. Which is crap since this thread is about the next person's perception of what beats the previous picture, and not about your perception of what the rest of us are supposed to be doing.
