i fucks with okcupid. i porked plenty of chicks from there. POF is kinda like the trailer trash version OKC. females on POF are kinda like on the lower end of the gene pool. OKC has tons of hipster females and ones who have established careers and been around the world, and have to post a picture of some shitty country they've travled to. Both are free.
