Straightdar

The Women's Motorcycle Contingent looked very leathergay, but my "straightdar" went off at a few of the women.

<G> It is 'gaydar' -- and mine has never been wrong so far... My 'straightdar' HAS been wrong once -- I mistook a lesbian for a straight girl (we became best of friends after that).

Gay or straight, we've all made incorrect assumptions about someone's sexual orientation, so the likelihood of “gaydar” or even “straightdar” as a meaningful idea is unlikely.
