jack rug - A rag you use to wipe the goo from your hands after you jack

A rag you use to wipe the goo from your hands after you jack off and your shirt is ruined.

My jack rug is my favorite part of my solo sessions. It's like a side dish to my snack.

I used my sister's face as my jack rug. She's not happy.

I used my jack rug to wipe my pants. Now it's ruined and I'm sad.
