The rape of the Lock

Okay, this story is kinda weird. I know it is supposed to be a humorous poem but I just found it odd. So this is what I got out of the poem: Belinda is very beautiful and she plays a game of cards with 3(?) gentlemen. She has a cool card called a Matadore and she thinks she can win the game. I think it said she beat the first two people but that she lost to the Baron. Because she lost to him, his prize was supposed to be a lock of her hair. I guess when he did take the hair, she freaked out and "Not louder shrieks to pitying heaven are cast." This is where I got confused.. it starts talking about greek and roman mythology and somehow tying in the Gods to this situation?? So she wants her hair back and threatens the Baron with a bodkin(dagger). He says that his only regret if he died would be leaving her behind. What I am mostly confused about is why she freaked out so much. Earlier in the poem when he is about to cut off her hair, it says that in her heart she wants the Baron to succeed. I don't know, hopefully we talk about that tomorrow!
