The phrase is everyday Brazilian Portuguese slang with an explicit meaning, and the clip circulates in its censored written form as ah eu vou g*za. Its exact recording source is not widely documented, so the sound spread mainly through meme pages, short video edits and soundboards where short Portuguese reactions are reused as punchlines. Brazilian meme culture often recycles blunt voice lines out of context, and this one survives because the wording is instantly recognisable to Portuguese speakers while the exaggerated delivery still reads as comedy to everyone else.
