It's actually a family joke, when one of us had shit mouth my father would always say Jesus put some gum in your mouth, your breath smells like a buffalo fart. So maybe in college as part of the pranks those fellas would do maybe they smelled the asses of buffalo's, I don't know. It's also the last bit of smoke left over in a bong that you couldn't fully pull all the way. And yes I'm retarded and can't remember any of my passwords for anything, that's a given though.
