go up to hug her, but secretly have your hoo haa out at the same time, so that when you hug her you piss all over her, then stuff on her front door step, and then using that stuff take your underwear and smear the stuff all over, then find her bedroom window and stick your poo covered underwear onto her window.
she will be so thoroughly disgusted and mindforgeted that she'll have to go out with you :D
