She is saying that she doesn't need this dude and his money to feel "sleazy". He is trying to get her to sleep with him, but she refuses hence "sick of all your lines so cheezy, sorry daddy boy I'm not that easy". And she is saying that he is missing out "You can't imagine the immensity of the fuck I'm not giving you". She would rather be with her friends drinking cheap booze that she stole, than be with him and his money.
