Bon, on fait quoi translates literally as well, what are we doing, and in online video it functions as a universal shorthand for indecision. The clip is short enough to loop as a reaction to cancelled plans, lost games, failed recipes and other everyday dead ends, and its French phrasing gives it a slightly different flavour from the usual English reaction sounds. Because the question is left unanswered, viewers fill in the next step themselves, which is why editors keep reaching for it for comedy sketches, vlogs and short-form reaction edits.
