Falsifiable is a quality that theories have. It means that the theory can be tested and therefore it can be found whether it is true or false. Some theories are not falsifiable. See the body below for an example of an unfalsifiable theory.
If I had a theory that all natural laws were implemented by little invisible elves it would not be falsifiable because the little invisible elves would be undetectable. Although immune to disproof, my theory, in the absence of positive evidence for its validity, would be considered highly unlikely and, according to Occam's Razor, since little invisible elves are not a necessary assumption in order to explain the natural phenomenon we observe (we could just assume that natural laws carry themselves out, or that they are just part of the dynamics of nature) we must abandon the little invisible elves theory of natural mechanics.
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.
