A sex move in which the male lays on top and does a superman (which is when he puts up all his limbs and is laying only on his stomach, like the pose superman does when he's flying) and then he urinate in the recipent's vagina or anal region, depending on which side the male is on.
I can't believe you did a GoldenAge Superman with Julie! That must have been painful!
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.
