This is what you call someone when they are being obnoxious, annoying, stupid, lame, or if they are rambling. This word may be confused with the animal, the newt, but if you are questioned, just spell it out for them.

Stevie: Yeah, he is a true knute.
Yo, when I pulled out my knute, she almost passed out when she saw the size of the thing.
