And, unfortunately, I fear those statements are not false at all - they are forewarning and really isn't that bad comparative to the rest of YouTube.
Are you talking about what is usually understood under that term, i.e. sexually explicit content?
No. I referred that which all adult human beings deal with - curses, that sort of thing.
Sexually explicit content is incredibly hard and nigh impossible to find on youtube, and certainly not in the land of YTP.
At least, not that YTP... YTP is effects, sentence mixing, word splicing, using sources that are otherwise clean or such (for instance, Billy Mays, Hotel Mario, Beauty and the Beast) and creating 'poops' from them. Styles vary wildly, some more like Dinnerwarrior focusing on mixing and splicing while others like Madanymous focus on CUHRAZY effects and that sort of thing.
