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.

Got your back

This originally came from old movies and TV shows where two people are in a dangerous situation (usually hunting criminals or other enemies), and one of them is going to venture forward. The other person stays behind and watches for any danger coming from behind or other directions that the first person is unlikely to see. The one who stays behind typically has a weapon, to fend off any attackers.

person 1: "I'm going to look behind that garage."

person 2: "Alright, I've got your back."
