Smart Alec is a self-assertive person with pretensions to smartness or cleverness. Smart Alec is informally used to refer to a person who is considered as a know-all or too wise or a clever clog. In the other sense it is used to describe a person’s erratic behaviour when he/she is arrogant, overconfident, brash, conceited or swollen –headed. According to Jack Handy, “If I lived back in the wild days, instead of carrying a six-gun in my holster, I'd carry a soldering iron. That way, if some smart-aleck cowboy said something like Hey, look. He's carrying a soldering iron and started laughing, and everybody else started laughing, I could just say, That's right, it's a soldering iron the soldering iron of justice."
