A short six-second voice clip of someone delivering the line 'it all just kinda happened' in a flat, matter-of-fact way. It lands as sheepish and resigned, like a shrug in audio form, turning an unexplained mess into something awkwardly funny instead of serious or dramatic for the listener hearing it.
