So the girl I was convinced was a mega lesbian goes "yeah me and my boyfriend went out last night." I played it cool but then she goes "you know you remind me of this gay guy I know...maybe I should hook you up...oh sorry I don't actually know if you are gay, I just assumed. You act very feminine." Then I laughed and said no, I am straight but I thought you were a lesbian because you are very tomboyish."
Just goes to show you. Then a bisexual girl piped up and said "I knew you were both straight, but this show how badly straight people's gaydars suck."
