I just re-watched that movie, and I noticed it has an inside joke in the end credits directed at some French b-movie website I frequent called Nanarland. The credits thank a guy named "Mr Promizoulin".

The word "Promizoulin", which doesn't mean anything in French either, is taken from the extra-badly dubbed French version of Zombie Lake: during the scene where the villagers psych themselves up to go fight the zombies, one of the dubbing actors flubs his line and yells "Yeeeeeah, promizoulin" (which is meaningless gibberish), and they left it in. So the word has become an inside joke on the site, used to express excitement.

So, half-drunken rambling aside, its just cool to see that somewhat mainstream movies are now playing along with internet fans.
