The phrase: "bag of broken antlers" refers to a very thin woman. She is so thin that having sex with her is like fucking a bag of broken antlers. She can hurt you with a hip bone or elbow. She has no padding on her at all. She often will have small breasts, and very likely wears a padded bra. Drug use can lead to this emaciated appearance, as can smoking and alcoholism.
1. After I ejaculated in her vagina, filling her full of goo, I noticed that I was sore all over. She is too thin and bony. She is like fucking a bag of broken antlers!

2. Those BBWs are great. You get to eat some good food after having sex with them, and they are not like fucking a bag of broken antlers.
