1.
The shot in porn where all you see is the dude's asshole and balls slapping against whoever they are fucking.
How am I supposed to watch porn when all I see is Undercrown?

An undercown is that shot in porn where all you see is the dude's asshole, and balls, often switched to right after some hot and heavy action, in order to make the viewer dump his load to the view of a man's sweaty balls
