Sack-Slapper

When your sitting on the toilet dropping the kids off at the pool and the crap keeps coming out in a single piece until it finally breaks off and slaps against your ball sack.

I was sitting on the toilet and the turd was so long that it hit the bottom of the bowl and continued to work its way up the side. When it finally dropped from my ass it slapped my ball sack thus being termed a Sack-Slapper.
