The phrase comes from Brazilian meme culture built around Goku from Dragon Ball, where short dubbed lines are reused as reaction sounds. Clips like this spread through WhatsApp groups, TikTok edits and soundboards because the meaning is clear even out of context and the delivery is instantly recognisable. It stays popular as a quick agreement sound, similar in spirit to other short reaction memes that creators drop in for timing rather than explanation, letting a familiar character say the obvious part for them.

Goku saying é isso mesmo in Portuguese is a short Dragon Ball voice clip used as a reaction meme for confirming something funny or obvious online.
This is a very short voice clip of Goku delivering the Portuguese phrase é isso mesmo, meaning that is exactly right. The line is spoken with confident, upbeat energy, like a quick confirmation rather than a dramatic speech. Because it lasts just over a second, it lands as an instant punchline, giving the feeling that Goku himself is agreeing with whatever was just said or shown. Viewers hear it as both a familiar anime voice and a funny seal of approval, which makes even a simple moment feel exaggerated, certain and final.
