I encountered this situation when answering this question. I could make a much more convincing argument if I used one high profanity example. (And I don't know if I can use that example as an example on meta to get you people more clear idea). Some hints are,
- As the question was about nature of holes, example contained a hole.
- Involving a type a sexual intercourse some people consider unnatural.
I hope you see where I am going. If not and if the rules allow, ask me, Ill explain in edit/comments.
