As a piece of online meme audio, this clip works because its meaning travels even for listeners who do not speak French, with ouais signalling agreement and la vie framing whatever just happened as simply part of life. Short reaction sounds like this spread through soundboards and short-form video, where a single recognisable voice line can carry an entire joke without explanation. Its staying power comes from that flexibility, since the same weary tone fits a minor inconvenience, a failed attempt, or an ironic twist just as well as a bigger disappointment.
