The huehuehue laugh comes from the 'BR' stereotype of online gaming, where Brazilian players became famous for spamming 'huehuehue' in chat, a phonetic spelling of their giggle. The joke took off across imageboard and forum culture, and this clip is labeled as part of a lulz compilation from a /b/ board troupe, the kind of sound pack chan users assembled for trolling. Years later the laugh still shows up in memes, reaction videos and game streams whenever someone wants a quick, unmistakable 'got you' sound.
