refers to a girl that is mostly on the lesbian end of bisexuality. the term "69 percent" is a homonym, referring both to the percentage of lesbian and her favorite sex position. 69 percenters are the holy grail for every man, signifying not only a tougher challenge to bring to bed, but also the most likely girl to bring along a friend for a threesome.
"i'm not really that into guys, though i do enjoy them on rare occasion. i'm definitely at 69 percent."
"she's such a babe man. i thought she was a lipstick lesbian but it turns out shes just picky about her men. that chick is a 69 percent."
