Straigt date is when there are
two of the same sex on a date
together. And one of which is is gay. The other is usually not out of the
closet hence they call it a "straight date".
Two guys, one 32 years old, the other 22 were out at the wine
bar together. The older one made it very know to everyone in his vacinity that he was gay, and had "partners". The other one
made references all night to a "girlfriend". But in the end they were two guys in a wine
bar together and they were on a "straight date".
