The phrase is Portuguese for selfish, that is what you are, and the clip circulates online as a short spoken meme rather than as a song or sound effect. Its appeal comes from the directness of the wording, which needs no setup and can be dropped into comment threads, edits, and group chats whenever someone acts self-centered. Because the line is in Portuguese, it is especially shared among Portuguese-speaking users, but the confrontational delivery makes the intent clear even to listeners who only catch the tone.
