GO DIG YOUR OWN GRAVE!

1. When you want to murder someone in a hot tempered fury but in-spite of your anger you care so little for them that you'd rather that they dig a hole six feet deep and 6 feet long with a shovel and after doing such back braking labor climb inside of said hole and bury them self alive so you don't have to do it for them.

2. when used repeatedly it implies they should undertake this task right now and stop doing anything else they might've been doing or have planed for the rest of there life.
