Vo Quitar comes from the Brazilian Portuguese phrase vou quitar, a casual way of saying I am going to quit or log off, widely understood as tchau, meaning bye. The shortened spelling matches how people type it in chats and on soundboards. Online it spread as a reaction clip for leaving games, calls and threads without a long explanation. Its popularity comes from how blunt and relatable the exit is, turning an ordinary goodbye into a short joke that works even for viewers who do not speak Portuguese fluently at all.
