sniss 

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.

sniss 

when a man pisses and sneezes at the same time thus losing control over the projection of his piss

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