Look at that girl who acts like she is friends with everybody, she's hella Duffy.
That girl that flirts with everyone is a Duffy.
"hey man I got you a ticket to the superbowl" "no way you're Duffy."

You are such a duffy. I told you twice already. You work at the big grey building overlooking the Ottawa river.

Duffy or ‘Duffball’ as he is better known (apparently it’s because he has only one testicle) is the class joker. He is a complete legend and tells all the best jokes, although most of them are pretty bad. His most commonly used words are wasteman, big-man and Dracula. His most common catchphrase is ‘Glyn is a G’.
