Does T-rex say a swear word in Jp 1?

in the scene where it's raining, and Dr. Grant and the kids get away from the jeep, while T-rex tries to hunt them down , everyone gets away by climblng down the ledge. The next scene shows T-rex looking into the camera and giving off a Big T-rex roar. I think that T-rex is saying a cuss word or swearing, since his meal got away. What do you think?
