I could see him sitting at a big old table full of food, just stuffing his big old fat face, and then he starts to choke on a big old piece of meat, and he starts gagging and spewing food, and his eyes start to bulge out, and they're watering, and his veins are popping out …

Вопрос:

1. Почему по-русски набивать рот, а по-английский to stuff one's face; целоваться в губы = to kiss on the mouth; облизываться = to lick one's lips?
2. Какую семантику имеет слово old в сочетании с big в приведенном выше отрывке?
