Little is known about the original recording behind Nejejeejejej, and the title appears to be a phonetic spelling of the garbled sound itself rather than a quote from a known show. Clips with nonsense titles like this often spread through soundboards and short reposts, where users save them for the sound alone instead of the source. Its appeal comes from that lack of context, since the clip can fit almost any silly reaction, failed joke, or confusing exchange without needing an explanation or setup from the viewer at all.
