pencil holder 

The phenomenon of the fat kid's pants sliding down his butt just enough when he bends over to show some butt crack. Can also apply to the plumber and the cable guy.

The Thatcher brothers saw an opportunity to point out little Dougy's pencil holder to the other kids. They all got a good laugh when little Dougy started to cry about it.

Hillbilly pencil holder 

The buttcrack. You can keep your pencils there, if you flex.

I bent over to pick up the pencil I dropped, but my friend stuck his pencil in my crack and yelled "hillbilly pencil holder!"
