The creamy amalgam of sperm and smegma. Formulated when a dude with a filthy, dick cheese riddle penis beats off and nuts all over his knob and froths it together.
My roommate left is nasty as cum rag on the couch. It was covered in dried spergma.

I really need to wash my glans more often. This smegma really makes a lot of spergma when I rub one out.
