Adudu is the alien antagonist from BoBoiBoy, the Malaysian animated series that first aired in 2011 and became popular across Southeast Asia. In the show he constantly clashes with BoBoiBoy and his friends, so his complaints about the young hero became a recognisable part of his character. The phrase budak tu lagi, meaning that kid again, fits that running rivalry perfectly. Clipped from dialogue, it later circulated in Malay-language meme edits and short videos, where creators reuse it whenever a familiar troublemaker returns.
