When you sneeze so hard you piss your pants. Usually happens to middle-aged women.
While walking the dog my wife paused to sniss, she sneezed and pissed so we had to get home to get her out of those wet clothes.

I heard Bill sniss while he was in the bathroom and sure enough there was piss all over the toilet seat and the floor.
