YouTube Poop is an internet MeMe. I would like to make a free soundboard app in the app store (Yes, I'm in the $99 developer program). I was wondering what the legal ramifications would be. I could call the app YouChewPoop, maybe, after the website. I can't use the words Mario, Luigi, Zelda, etc..because they belong to Nintendo. How should I go about naming the app and the sound boards. Maybe instead of saying Mario I could spell it Mar0, i don't know.
