I have this friend who is in a contest to win a modelling contract with a swimwear company for broads. The contest is to see who can get the most "likes" on a couple facebook pictures.
She's fit to say the least and she shreds on a snowboard and a wakeboard... If you are a proponent of hot girls in bikinis on facebook, like her three pictures on this group- hers only.
Then tell all your hot girl friends to take similar pictures and put them as their profile picture.
