Você Também Errou comes from Brazilian band Banda Calypso, whose upbeat calypso-pop songs became widely popular in Brazil. The phrase itself means you also made a mistake, which gives the short excerpt a ready-made joke for online clips. As a soundboard sound, it is shared mainly for reaction videos, memes and short edits where one person points out that another person was wrong as well. Its appeal comes from the catchy vocal delivery and the instantly understood situation, rather than from needing to know the full song.
