About this sound
This 7.8-second clip is Manoel Gomes repeating the phrase 'aí aí aí' in a rhythmic, sing-song voice, with each repetition landing a little more insistently than the last. It feels playful, teasing and knowing, like a nudge to someone who has just been caught out or finally understood. It works best as a light, cheeky reaction rather than a serious comment.
