The phrase não apenas is everyday Portuguese for no, just or not, only, and online the clip is used less for its literal meaning than for its timing. Shared as a tiny reaction sound, it circulates in Brazilian and Portuguese-speaking meme edits, chat replies and short videos where a conversation needs an instant, understated correction. Because it lasts well under a second, editors can drop it over almost any pause or facial reaction, and its popularity comes from that flexibility rather than from a single famous scene or performance.
