This morning I read an article by a pretty serious UK journalist who, in a side comment, described a public figure as "mad". From the context I am puzzled whether he meant the figure
a) is clinically insane and likely in need of treatment or
b) (pejoratively) is very unpredictable or
c) (in awe) takes amazing risks.
Could he mean something else I haven't picked up on as I do not live in the UK ? As a UK English speaker what kind of connotations does "mad" have for you when used to describe a public figure? I have never thought of the figure in question being insane so this option intrigues me in a morbid way.
Please keep the thread name free.
