Coronated

I am aghast to hear my former near neighbour, Mrs Theresa May, described as "coronated". 

There is no such verb, but which of the meanings of the adjective might be applicable to her? 

Has she a crest or a crownlike appendage? 

Is she girt about the spire with a row of tubercles or spines, as are certain spiral shells? 

Are her coronal feathers lengthened or otherwise distinguished?

Of course, these possibilities are not mutually exclusive.
