The feeling of loss or emptiness one has after an epic bowel movement. This feeling can be accompanied by separation anxiety mixed with a feeling of euphoria. In most cases, a feeling of "lightness" or "lightening" may be experienced.
The day after eating at that Brazilian steakhouse followed by 2 cups of coffee I suffered from Post Pootum Depression.

Last night I sat staring at the wall, feeling empty, like a big part of me was just flushed away. I think I was suffering from Post Pootum Depression.
