Little is publicly documented about the original recording behind Grote Blij, so its appeal online comes mainly from the phrase itself and the feeling it carries. Dutch speakers will recognise grote blij as a simple expression of being very happy, which makes the clip easy to reuse even without knowing its first appearance. On soundboards it sits alongside short reaction clips, where listeners can find it quickly, play it for a joke, or drop it into a meme. That word-of-mouth, clip-by-clip spread is typical of small spoken sounds that survive because they are instantly understandable.
