Put this clip right after the quote you are reacting to, while the speaker is still on screen, then follow it with the Ceeday Huh sound for a second beat, or close the sequence with a Damn reaction when you want the last word on what was just said.

This is an 8.6-second voice clip of someone asking 'O que foi que voce disse?' — Portuguese for 'what did you say?' — in a drawn-out, incredulous delivery. It lands as pure disbelief, the kind of stunned, slightly offended reaction you give when a comment is so bold or absurd you need it repeated before you can even respond.
