I honestly tried it once. It was when I was 18, and I was extremly overwieght. I was being serious, but she thought it was funny and laughed at me. It sucked, cuz I had never been laid and I was thinking, we were at this party, sure she wants me. Little did I know that hot chicks don't dig really fat guys.
now I am in much better shape, and that line still does not work, it never will.
If you must insist on saying it, then good luck ,but I will not participate in these barbarian games you like to play.
