Badbutt just means you are tough. There is nothing derogatory about that. Jackbutt just means your are stubborn like a mule. Dumbbutt and Jerkbutt are what the first word says, either dumb or a jerk. As for smartbutt, it means you are sarcastic. Personally, as long as you are not being wildly inappropriate, I see nothing wrong with a little sarcasm. And like my daddy told me, it is better to be a smartbutt than a dumbbutt.
