Obscene

What is obscene?
From wikipedia, we got this:

Obscenity is a term that is most often used in a context to describe expressions (words, images, actions) that offend the prevalent sexual morality of the time.

Despite its long formal and informal use with a sexual connotation, the word still retains the meanings of "inspiring disgust" and even "inauspicious; ill-omened", as in such uses as "obscene profits", "the obscenity of war", etc. It can simply be used to mean profanity, or it can mean anything that is taboo, indecent, abhorrent, or disgusting.
