means A person or thing that resembles or behaves like something from an earlier era, or a deliberate callback to that earlier style.

from Straightforward compound of 'throw' + 'back' — originally used from the 19th century for a reversion to an ancestral type, especially in breeding and genetics, where an offspring 'throws back' to traits of a distant forebear rather than its immediate parents. The sense later broadened from biology into everyday use for anything that harks back to an older style or time — and eventually into internet shorthand ('Throwback Thursday') for curated nostalgia posted for an audience.
