When you go into a restroom with flip flops and the person next to you is splattering piss on your feet. Or in rare occasions it can be your own.
My girlfriend asked me why my feet were all wet after leaving the restroom at the state fair. I explained to her that I was just pisstall whipped in there, but it's ok.. my feet were hot.
"Look at this scary fundamentalist Web site. I can't believe that anyone would say such things and mean them." "They don't. It's obviously a pisstake."
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.
