Maybe you have to be a fan of the movie, maybe not. For all the random Spanish I might know, it's really not speakable Spanish so much as restaurant lingo. The hard part for me here is trying to remember the original bit that Jay says. So here are both. They do say the F word a lot (seriously, a lot) and a few other choice things. If you don't like it, I'd suggest you not click either link. Is it just as offensive en Espanol even if, though you don't understand, you know what they are saying? I kind of hope so!
