Jack-cunt
Jack the Cunt is a guy who is both unbearable and a complete f***ing idiot all at once, especially if his name is Jack.
Jack the Cunt just sat there and laughed while the rest of us did all the work.
He called me a f***ing idiot for no reason and then left before the project was done.
He said he was going to help, then he went to get pizza and came back when we were already finished.
