Abby, to answer your question, there are several basic questions to answer. First, what is considered profane(correct spelling, in case you were wondering)? If it describes a body part, does that make it profane? If it describes a sex-act, does that make it profane? What if you made it up, but it has a bad meaning, does that make it profane? It all depends on where you draw the line on profanity. I only ask that you use your best judgement on what is "appropriate." But, yes it is allowed, in moderation.
Liz, to answer your question, yes, I have infact noticed that orange juice is very "un-orange."

Thank you and have a nice day, n00b.
