Libel is a small word for a big accusation. Actually, you might say it encompasses accusations on either side. There is the person who is pointing the finger at you, and then you are accusing him/her of libelling you. The person badmouthing you has had scurrilous things to say about you. The slurs are false, you say. Whom to believe? It may just end up with one big “See you in court” moment. Perhaps even one that is expressed in ALL CAPS!
