this girl is really his hand, that he is going home to masterbate with. hold it up and the fingers spell out J-i-l-l.
makes him sound cool, even though everyone knows he's pathetic and can't get any.
guy2: "yeah me too, i met this fucking hot chick named Jill."
On top of all that she has also a great personality, very social and musically inclined. Her interests are extremely broad which makes her even more to die for.
Everyone should at least have one Jill in his/her life.
You won't regret it.
Look man, I bet here name's "Jill"!
Man, there should be more Jill's in this world.
If you can get over your jealousy and get to know her, she will be the best person you've ever met.
If you look up charisma in the dictionary, there's a picture of Jill.
