Pretty Little Liars: Who is Paul Var Jack?

Who is Paul Var Jack?

We all know that Alison is in love with

movie Breakfast at Tiffany's she uses the name Holly Go Lightly as one of her many alliances. So is A tauting her by going by the Paul Var jack or is this just another one of Allison lies. I looked up the meaning for Paul Var jack and came up with something very interesting. Paul Var jack in the urban dictionary means going from ugly to not ugly or not likable to likable. This term can apply to any man and this term applies to men only. So could this be a clue of who A is because couple of characters on the show have went from I would not say ugly to not ugly, but they have made a big improvement in there appearance. So did A take this term and twist into something sinister or is he or she using this against the Liars to torment them. New clues could Andrew be the Paul Var Jack that the girls could be looking for and using his relationship with Aria to mask it.
