Pissmosis

When you're taking a piss and you have foreskin but you don't roll it back and your piss puts pressure on your foreskin.

"Wow man that pissmosis was so high-pressure it lifted my foreskin a good few centimeters ."

cumosis

When you cum but you close off your foreskin in some manner so your cum stays in your foreskin and stretches your foreskin like a water balloon.

"Lol I just blasted Jenny with the biggest cumosis."
