The phrase means oh, how nice in Portuguese, and this clip is shared mainly as a short sarcasm reaction rather than as a line tied to a specific film, show or celebrity. Its popularity comes from how easily the tone translates even for listeners who do not speak Portuguese, because the stretched vowel and flat delivery signal irony on their own. On soundboards and in short-form videos it circulates alongside other mocking reaction sounds, used whenever a creator wants to pretend to be impressed while making clear they are not.
