The phrase is Indonesian slang built around Krabby, a nickname for Mr. Krabs from SpongeBob SquarePants, paired with gendut, meaning fat or chubby. The clip is credited to Krabs TV on the soundboard and runs for just over two seconds, which suits short-form edits and reaction videos. It spread mainly as a user-shared meme sound rather than as a line from a specific episode, and creators keep using it because the joke is visual and immediate: one short phrase is enough to label a character as greedy, round, or overindulgent.
