The speaker seems worn down by a social scene that demands constant appetite and constant chatter. "Hip and hungry places" suggests trendy spots where people go to eat, drink, and be seen, and the speaker feels pushed into them, almost against their will. "Force me to get bit" is a sharp, slightly comic phrase: it could mean a bite of food, but it also hints at being nipped at, stung, or used up by the crowd.
The last lines turn inward. The speaker's aches are "eating" them, so the hunger of those places is matched by a hunger inside the body. "Full of talk about talk" sounds like empty, self-regarding conversation that fills you up without feeding you. Then the closing image, "my head is all oven," gives a feeling of heat, pressure, and overload, as if too much noise has cooked the mind. The mood is tense, tired, and a little darkly funny. The title, "Flaquito," is a Spanish word meaning something like "skinny" or "thin," which may echo that sense of being hollowed out, though the poem never says so directly.
