When some chick/guy that you want to screw/date that lives in the same town as you. They find you unattractive compared to another guy/girl that has the same looks, traits, money, etc. but are more than willing to become friends because they are 'from away'.
Guy: Hey I've known you for quite sometime and he have some good times together, do you want to go out on a date?
Girl: No, I don't think so. Oh! That reminds me! John has the same exact car you do, and you both look so much alike, and he just moved here from New York City. We're going out tonight! He's so hot!
Guy: I hate sluts with Geopreference Disorder!
