The clip is listed as a pegadinha from João Kleber, the Brazilian television presenter long associated with hidden camera pranks and teasing studio segments. In Brazil, pegadinha means a practical joke played on an unsuspecting person, and the hihihi laugh became the audio shorthand for that mischief. Shared on soundboards and in meme edits, it now travels far beyond the original broadcast, much like the baby laughing meme, as a quick sign that someone is joking, winding someone up, or laughing at a harmless embarrassment.

A short hihihi giggling laugh from João Kleber prank shows, used as a cheeky reaction sound for teasing friends, jokes and silly fails online.
This is a short, high pitched giggling laugh stretched out as hihihi, the kind of mischievous chuckle heard in a Brazilian prank segment. The laugh starts light and keeps bubbling, sounding smug, teasing and a little bit naughty without any words behind it. It works because everyone instantly reads it as someone enjoying a joke at another person's expense. Dropped over a reaction shot or a failed attempt, it turns an ordinary moment into a playful wind up, making the target look caught out while the audience feels in on the prank.
