The most heart wrenching feeling known to human kind. The feeling when they are your everything....but to them...you may be nothing. The feeling of never having the satisfaction of knowing if your feelings are returned. Never knowing if to them you are just another insignificant person they meet in their life. You will also probably never get over them. So continue to never miss a day of school, just in case something happens. Continue to try and walk past them in hopes that you might stick out of the crowd. Continue to talk loudly near them in hopes that they might think you more interesting than anyone else. And continue to think you ever stood a chance.
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.
