My close friend from high school joined up with a co-ed fraternity and since lils and bigs were co-ed, it wasn't unheard of. (She mentioned that it was stereotypical, but that was her opinion.)
i do believe this happens, but EEW. as far as my big bro is concerned, he is my big bro and that is IT. i just kinda thought your big bro/sis whatever was chosen b/c they fit that specific criteria....and being attracted to them in any way doesn't really fit in there anywhere for me.....and i'm in kentucky! however, my BB did inform me drunk one night that he was "in love" with me.....and i think i was trauamatized for life. (ilovemyglo, you're trauamatized now, too, huh?!)

we don't have "big bros" for our girls, but we do have switch day bigs during pledging. It worked out that two girls this year are dating their switch day bigs (from different fraternities) but it's pretty cute and they are good couples.
