A person considered socially unacceptable or at the least tolerable within certain perameters and under strictly defined conditions, whose behaviour puts him at odds with the greater dramatis personae of human life. Often
given to inapproriate remarks and outbursts the like of which
may provoke verbal antagonism and, in extreme cases, physical violence against the sayer thereof. Various types of sex pest and stalkers
fit the description. As do recluses, political fanatics, angry loners and comic
book collectors.
"Why did your friend ask to see my wife's 'vital statistics' at the dinner
table? And what on
earth does he
mean?"
"I don't know, pal. He's just a bloody weirdo."
