(n) When a sexually confused (and ultimately gay) man "tries" having sex with a woman who is his closest friend to determine his sexual orientation, similarly to how, in the sitcom "Will and Grace", Will verifies that he is gay by trying to have sex with Grace.
Sally: Yep, he came over last night, we had some wine, one thing led to another, and... well, let's just say we totally had a will and grace moment... He is definitely gay.
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.
