Well, at the last convention I went to, my roommates bought a trove of Tiger & Bunny R18 doujins and they had a massive reading party. They just made up whatever lines they wanted and read it that way. Sometimes they didn't even bother to read right-to-left. And none of them read Japanese at all, and they only asked me what one thing actually was. It was hilarious.
So you can definitely do it for the lols, man.
