Questions about example sentences with, and the definition and usage of "Obscenity"

A: Usually 'obscene' means disgusting or inappropriate. So here maybe it's implying the empty mouth is unnerving, disgusting, or wrong.

A: It basically means that when the pilot was warned by the air traffic controller, the pilot did not take it seriously and responded with something like "F*** your mother."

"Obscenity" is a statement, depiction, or action that is extremely inappropriate and offensive.

A: Bawdry is a very old and unusual word, you won't hear it very often. Most often you will hear dirty, naughty, risque, etc instead. All of these are usually used as describing a joke or song which has sexual innuendo, but is not extremely graphic.

obscene/obscenity is for more graphic, unacceptable content (porn, very graphic rap lyrics, etc) . This can be both a legal term (some obscene content does not get 1st amendment protection), as well as a social term.

The difference between the two is subjective. A high class, religious, conservative old woman might think a regular dirty joke is obscene.
