Stoneface is a game played with one female, a group of males, and a table. The female positions herself under the table. The males sit around the same table. The female then performs oral sex on one of the males. The object of the game is for the males to guess who is receiving oral sex.
When Danielleplayed stoneface with the boys, Ted couldn't keep a straight face and gave himself away.
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.
