A guy who acts like a total idiot to girls, especially when he's trying to impress them. He's so dumb he can't even get laid by a girl who's half broken, but he'll still try to hook up with a fat girl just because she's easy.
My ex was a j-hart. He would call me names and then ask me out the next day.
My cousin's j-hart friend tried to flirt with my mom and got called a loser.
My teacher said my friend is a j-hart because he failed math and still thinks he's cool.
