A short voice clip of someone chanting nananana booboo in a sing-song, teasing rhythm, stretched over about two seconds. It lands as smug and childishly triumphant, like a playground taunt aimed at someone who just lost, missed out, or got caught out, giving the listener that petty, gleeful feeling of having gotten away with something.
