This kind of exaggerated laugh is widely used in meme edits, short reactions and reposted joke videos across social platforms. The exact source of this specific clip is not clear from the available information, but it fits the same family of absurd reaction audio as goofy ahh sounds. Creators keep using it because a long laugh can stretch out a joke, make a bad take feel more embarrassing, or add a deliberately unserious tone without needing any spoken setup.
