In everyday Spanish, especially Rioplatense slang, re works as an intensifier, so es que está re rico means something is really, really tasty rather than just good. That blunt, relatable wording is why the clip travels well as a reaction sound: it needs no setup, translates through tone even for listeners who speak little Spanish, and fits the fast pace of short-form video. Creators reuse it for food reviews, cooking clips and taste tests, where a two-second verdict can carry the whole joke.
