Adudu is the scheming alien villain from the Malaysian animated series BoBoiBoy, known for his constant plots against the young heroes. His exaggerated bwahaha laugh became one of his most recognisable traits in clips shared by fans online, where it was cut out and reused far beyond the original episodes. On TikTok, YouTube and meme edits, the laugh now works as instant shorthand for a villainous plan, a sneaky trick or a joke going exactly as intended, which is why it remains popular years after viewers first heard it.
