Good Times!
I bought this flick when it came out on DVD, and here's what I like to do with people who've never seen SNUFF.
First mention that you randomly bought a DVD from a tag sale or consignment shop, the only info you know about it is that it's loosely based on the Manson Family, watch the flick with them, be like, "this s**t's bootleg as *beep* There's no menu or anything!", watch their reaction at the end, play along with them, get drunk or high while you're watchin' it, that helps too. Good Times!
