I just realized this... Holy shit Facebook has audio messages you can send
My friend started sending me audio messages.
And it just hit me. This is an excellent way to convey your awesomeness to a girl in a manner she can easily digest without having to pick up the phone.
You can also do it through text. Had so much fun doing it. Only did it with one girls so dunno how effective it is. It's good in that you have more chances to get it right, vs voicemail where you only get one chance and it also makes you stand out because no one does it.
