great ass

1. A term used to describe someone who actually has a great ass.
2. A term used by those who do not actually know if the person they are speaking of actually has a great ass. They just see that they are hot, look at their rump, and say that they have a great ass without knowing the actual quality of said ass.

Tenpenny: "Look at Jill's rump. My, she has a great ass."
Frank: "Jill's face is really great, but she is flat as a pancake in the back, you silly fuck."
