Hmm, I don’t see how semicolons work in this sentence.
Marking up the sentence with extras to help visualize:
Buffalo-buffalo (who) Buffalo-buffalo (do) buffalo (in return also) buffalo (the other) Buffalo-buffalo.
A sentence of similar structure, subbing components for others of the same language parts…
- Buffalo buffalo → other nouns qualified by adjectives
- Foreign cars
- Austin techbros
- big money
- buffalo (verb) → other verbs
- covet
- cost
… would be:
Foreign cars Austin techbros covet cost big money.
(edit: I couldn’t quickly think of a location adjective for the last noun, which would have stuck to the pattern more closely, but “big” is still the same role, an adjective.)
