Indecency is the habit or action of being offensive or improper. Indecency is banned on television during times that children might be watching.
If you tell dirty jokes or deeply offend a friend, you could be accused of indecency. Swearing on a radio broadcast or showing an extremely violent scene in a movie meant for kids are both examples of indecency that are punishable by law. Indecency comes from the Latin word indecentem, "not decent" or "in bad taste," from the roots in-, "not," and decentem, "fitting or proper."
