pain-a-back
A Jamaican way of saying your back is so sore from getting too much love, it’s like you’ve been kicked by a donkey.
I got pain-a-back after my mom's surprise love session. I thought she was going to kill me.
My back feels like it was hit with a hammer. That’s pain-a-back for sure.
After that wild night, I had pain-a-back so bad, I could barely breathe.
