Ceridwen:
That has been discussed, though I don't know now if it had a thread 
of its own or not.  The most likely candidate would, in my opinion, 
be James, since he probably came to see Lily at her parents' before 
they were married.  Another possibility would be Sirius, who may have 
accompanied James on his visit to Lily.  It could have been Remus or 
Peter, on the same possibility that they came to see Lily with 
James.  Snape is a possibility, since he was a classmate of Lily's, 
and we now know they were both good at Potions.

I always thought it would be funny if Petunia meant Sirius.  I 
imagined a scenario where Sirius comes by with James, and Petunia 
falls for him.  When he snubs her, she starts calling him "that awful 
boy".  Of course, this would mean she either knew Sirius Black, the 
escaped criminal, was a wizard in PoA and connected to James, or she 
didn't connect the name to the person, so that's probably not it.  
Still, it was fun to think of before I started trying to connect dots!
