Place this clip at the end of a lingering-person scene as the final reaction, after a quick Ceeday Huh for the double-take, then follow it with Nelson's Ha-Ha! once the person finally walks off screen.

This is a short spoken clip, about four seconds long, of a man saying 'Pô, esse cara ainda tá aí?' in Portuguese, asking if that guy is still there. It feels exasperated and mildly disbelieving, like catching someone lingering long after their moment passed. The line is credited to Leandro Copperfield.
