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".
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
