rotten in the back 

When there is residual shit rimming around your anus after defecating as a result of not wiping completely. Oftentimes, a fellow notices this when his/her butt hole becomes itchy or they scratch and sniff only to realize they smell rotten.

Honey, don't touch down there. I'm rotten in the back.
