How can i be "original" when asking a girl out?

So there is this girl on facebook (i have no idea how we became friends on there, nor have we ever gone to so much as the same high school), but i think she is very cute. Now there is no chance i will ever see this girl outside of facebook because i have no clue who she hangs out with, and i don't know where she lives (she doesn't live far from me, but i don't know the exact address). If i ever did run into her say at the mall or on campus i wouldn't hesitate to go up to her and ask her out, however i don't think that will ever be the case, unfortunently im going to have to ask her out over facebook if i ever want to see her. Now this girl constantly has guys telling her how beautiful she is and blah blah blah almost everyday on facebook. So one day i sparked up a conversation with her asking her if it ever gets old being told the same thing every single day, and asked her if some originality would be appreciated, to which she responded yes it would totally be nice if a guy could be original for once. Now heres the hard part how can i be that guy thats "original" when asking her out, because if i do what every other guy does and just continuously compliment her appearance and blah blah blah i will get exactly were there have gotten, and that is absolutely no where (by the way not looking to have sex with this girl or anything just really want to get to know her). So help me out guys what should i do?
