A term used to describe a guy who wants to be cool but just ends up being more annoying than an 8 year old with ADHD who just drank 5 gallons of sugar-laden Kool-Aid.

(Note: Referred to as a "guy", although technically not a male - a large, untrimmed vag with pubic lice can be seen where the penis is usually found on a man.)
Girl: Do you hear that irritating motherfucker? Why is he fully grown, but still acts like my little sister in elementary school??

Guy: Yeah, he's a total Kerns. People always want to bitchslap the shit out of him, but it would feel too much like child abuse.
