Getting farted on during sex. (A sirocco is a hot wind from the desert)
Fuck, I got grossed out last night, dude! I was going the growl on my girl friend and she totally gave me a blue sirocco. She blamed it on the chili she had for lunch, but I think she did it on purpose.
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.
