Listed simply as wtf321 on user soundboards, this short laugh reaction has no confirmed original source, creator or release year. It spread the way many reaction clips do, by being ripped, reuploaded and dropped into short edits where a confused laugh was needed.

Its staying power comes from its brevity, it says confusion, disbelief and amusement all at once.
About this sound
A short voice clip of someone laughing and saying hahaha wtf was that, used as a confused reaction sound effect in memes, edits and gaming videos.
This is a brief vocal reaction built around uncontrollable laughter followed by a baffled 'hahaha wtf was that.' The delivery is loose and genuinely surprised, with the laugh spilling into the words rather than sounding performed. It captures that split second after something absurd, glitchy or completely unexpected happens on screen. Because the confusion is so obvious in the voice, viewers instantly read the moment as funny rather than serious. Creators use it to underline a weird event and let the reaction do the joking for them, without needing extra explanation or on-screen text.
