Can I call Napoleon Dynamite a 'cult-classic'? I think it definitely has a cult following but maybe it's not old enough to be a classic. Perhaps cult-favourite is better.
This movie is an endless source of inside-jokes among my friends and I, all the way from the obvious, 'GOSH!' to references about chatting online and llamas. I suppose they aren't really 'inside' because anyone who's seen the film will understand but I don't know too many people that have. If I see you wearing a 'Vote For Pedro' t-shirt, you are instantly placed at the top of my cool meter.
Thumb to pinky: 'Vote for Pedro', Napoleon, GOSH, Uncle Rico's Van, Debbie's note to Pedro.
