Re: Love and Monsters ... Who/What is Mr Skinner??

One of the episodes of "Doctor Who' being repeated by Our ABC tonight is
'Love and Monsters' where a group of weirdos is infiltrated by 'an
ordinary man', Mr Skinner, 'obsessed with the Doctor joins a group of
like-minded people hoping to meet the Time Lord in person'.
 
However, one of their members has a sinister motive and a harmless hobby
soon becomes a living nightmare. "Are you an absorbathon??"
 
Where does this 'ordinary man'/absorbathon originate from??
