"Franklined" is having one of your friends' try to hit on any female friend, ex girl friend, or sister of the people in your social group, even though he already has a grilfriend. This is normally done via text msg, myspace, facebook. It is usually done behind the back of the friends and normally results in rejection, but your friend will try and tell you hes in.
Mark: Hey Josh, you and that chick are getting pretty close now?
Josh: Yeah but Tom fucking franklined me, he found out that chicks myspace and now constantly tries to get with her even after she deleted and blocked him. He never meets women of his own.
Mark: No shit!? My ex just msged me and said he was doing the same thing to her, fucking franklined!
