someone who is completely obsessed with midgets/ people of a short stature (medically speaking of 127cm or less in height). People with this condition can't control themselves when they see 'little people', much to the embarrassment of those around them.
I was walking through the shops the other day with Anne-Maree, when she started whispering excitedly "look a midget, a midget, IT'S A MIDGET!!!!!"!! She's such a midgaphaeliac - totally obsessed. It's so embarrassing.
