pudnut

The noise that your nuts make when they slap against your butthole.

When you swing your nuts forward to backward, the noise it makes when your nuts hit your butthole is called a pudnut.

cruddy pudnut

A person who is always raining down on your parade. In other words, someone who is no fun at all.

My mom was being a cruddy pudnut because she wouldn't let me watch my show.
