My one brother calls Georgie Yak because he has gray hair on his head and black on his body he says he looks like a Yak. We don't like that too much, but my other brother calls him "little man" which is cute and I think Georgie likes that one better
I would be here all day with the nicknames I give him but the 2 most used are Porgie & Pa-Pa and sometimes I say Porgie Pa-Pa together.
