In Jurassic Park, after stealing the embryos and getting lost, Dennis Nedry has to tow his vehicle down a steep, but short hill. When he meets a Dilophosaurus (I am not going to point out the scientific inaccuracies with the design, since they are not relevant to the question), he says this when it doesn't move and just stares at him "No wonder you're extinct, I'm going to run you over when I get back down." After this, the Dilo spits in his face, and eats him in the car.
So, context aside, could the Dilo have understood what Nedry was saying, and just decided to make it so Nedry could not 'come back down'? All answers, please go by the movie, not the book.
