An annoying little piss ant

An inconsequential, irrelevant, or worthless person, insignificant and annoying, especially one who is irritating or contemptible out of proportion to his or her perceived significance.

A pissant is somebody who thinks he’s so damn smart, he can never keep his mouth shut. No matter what anybody says, he’s got to argue with it. You say you like something, and, by God, he’ll tell you why you’re wrong to like it. A pissant does his best to make you feel like a boob all the time. No matter what you say, he knows better.
