A knowsnowt is the person to whom you ask a question and are answered with a load of "Hmm, Let me see, Well, Basically, In a nut shell, Realistically, to be perfectly honest, You have to, Ok, Got it ? You understand or do you want me to explain again ?
He fills the reply with a load of big explaining words but never actually answers the question.
Fuckin Hell - If you ever have a problem, dont ask him, I was there for an hour, He's a fuckin "Knowsnowt".
