Place it at the end of a short exchange where authority changes hands, letting the claim close the scene. Pair it with the Bruh sound for a deadpan reaction beforehand, then follow it with Emotional Damage when the other person realises they have lost the argument.
About this sound
This is a short Portuguese voice clip, lasting about two and a half seconds, in which a man called Marco delivers the line 'Quem manda aqui sou eu' — 'I'm the one in charge here' — in a firm, self-assured tone. It feels bold and playfully bossy, like a quick claim of authority meant to settle an argument with humour rather than anger.
