The original meaning of a smart ass in common terminalogy is a person who "thinks they know" how to do or what to do and tries to inject their opinion or effort "thinking they know better, when they really don't.

A dumbass is a person who "doesn't know" how to do or what to do and tries to either inject their opinion or effort not knowing what they are doing.

Don't believe me as someone who has true intellect that is older then 80yrs and they can tell you I am speaking what they learned. I was young and asked many people who all were my grandparents age, I am 39 currently and I am said to have an old soul however that is a phrase for wisdom beyond my years. Meaning I collected knowledge form people quite q bit older to have an understanding of the true definition of words we have since lost our foundation and it would be nice to get it back or retain what little we still have here in the USA
Jeff gets a prefab item that looks simple to put together, the instructions are in the box, he puts it together before reading the instructions and has left over pieces, he doen't know where they go.

(when all else fails read the instructions Smartass)

Phil gets the same prefab item and instuctions, he reads the instructions and doesn't understand what the instrucions are saying and still tries to put it together and has the same left over pieces.

(when all else fails and the instructions are beyond your grasp ask for help Dumbass)

Jerry gets the same prefab item and instructions and follows the directions, he has no left over pieces when it is completed. He comments on Phil as a Smartass and Jeff as a Dumbass and says your both stupid. Therefore he is a Wiseass and a Jackass for the uncalled for commentary, with the smartaleck remarks.

Someone who is sacastic, in a cutting yet witty manner. A person capable of making a remark that could be interpreted as a insult or a joke depending on the sensitivity of the listener and the specific situation. A smart ass is not necessarily a bad person just usually perceptive. ( For terms to refer to an offensive, cruel and asinine person see Jerk, Asshole , idiot, fool etc.)
We were out the other night at the club when this jerk tried to pick up Nick's girlfriend, rather than fight he calmly stepped in and said, 'Look buddy you mother is could never be this PHAT (pretty hot and tempting) you gotta face only a mother could love. Nick's such a smart ass.

A person who just has to make everything make sense. Speaking of which, smartass is a oxymoron because an ass is a stupid person so smartass means "smart stupid person".
(not exactly the opposite of dumbass because a dumbass really is an idiot but a smartass isnt neccessarily a genius)
I guess this definition makes me a smartass
