all hot girls already have a boyfriend.. that's obvious.. and if she don't, then it's because she has some mental issues..
so move on, to the regular chicks...
remember, that a hot chick, gets approached by 200 males every day, and she can select which one she wants, so it's almost impossible to find a hot chick with no boyfriend.
and if you ever do, you need to be cooler, richer, nicer, better looking than the other 199 males that apporached her that day.
