Jack-cunt
A Jack-cunt is a total waste of space who acts like a cunt and tries to make everyone else lose their mind.
Jack-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.
