Bastardization of the term 'Brownie points'.
The term refers to how close a man is to being allowed anal sex by his partner. Brown-eye points being earned by good deeds and therefore having more of them means the likelyhood of being allowed the sexual act is greater.
Guy 1: My wife still won't let me try anal.
Guy 2: Obviously you haven't earned enough brown-eye points yet.
Points scored and acquired, from partners, for the use of that one instance they can't deny anal sex.
"My girl says when I get 10 Brown-eye points, I get a free pass to that ass. I scored 2 last night by paying attention when she was blabbering to her friends."
