It's a fact of life, some people use Xbox Live to hit on the chicks. The same tired pick-up lines get old after a while though. "You must be tired because you've been running through my mind all day" and "Do you have a quarter? My mom told me to call her when I fell in love" will get you nowhere with the gamer girls.
So check out these original Halo-inspired pick-up lines. One of the keys of success with using lines is originality. If the girl has heard it before, it probably won't work. So rest assured these haven't been used yet and therefore increase your chances of scoring.
