What does Genesis 25:30 mean?

Esau came in from the fields, exhausted and starving. He saw the stew Jacob was cooking and said, 'Quick, let me have some of that red stew—I'm about to collapse.' That's why people started calling him Edom, which means 'red.' Genesis 25:30 - Modern Text Bible

(Esau is desperate and impulsive, focused only on his immediate hunger. The nickname 'Edom' comes from this moment, tying his identity to this choice.)
