[TOMDM]

Why just make up a definition?

From the oxford dictionary:

Noun: speak to or treat with disrespect or scornful abuse.

Verb: a disrespectful or scornfully abusive remark or act.

Note the lack of personhood in those definitions. I can insult an object, event, person, corporation or even an idea.

[cluckindan]

The definition is from the Cambridge dictionary.
