Ten Ring 

A reference to the center ring on a silhouette target at a shooting range, worth 10 points. It can refer to the ten ring on the target itself, or the equivalent position on a human body.

That guy was a pro- he took him down with one shot, straight through the ten ring.

TEN RING 

the entrance to the asshole; the ringlike imprints that form the anal lining; essentially, one's shitblaster or fart box.

After ramming the biatch in her slimy hatchet wound, I flipped her over and crammed 8 inches in her 10-ring!
