lol.....white knight  are the guys who annoy the shit out of your girlfriend openly  knowing she's in a relationship with you,  getting plowed by you on a regular basis and still don't seem to care. 

   These are the same guys who come running  licking  their chops the moment you break up even though they know you've had your cock down her throat every day for the past 6 months. . This is why you see hot chicks with betas as rebounds.  Heres a top- find a girl at the right time when she's vulnerable or has an asshole boyfriend like myself,  tell her how perfect she is and watch those thighs  legs open up.
