Broadly equivalent to Jack Shit, Diddly Squat, etc.

Jack

Jack is a disrespectful person, who you can't trust. He will turn on you. He is gay as anything. He gets jealous easily and he is a pure cunt. He doesn't deserve to live. He cannot be a friend without him teasing, bullying you.

Oh your a dickhead your name must be Jack
