This sound circulates online mainly as a Dutch reaction meme rather than a widely documented quote from a major film or TV source. Its spread comes from the strange wording and delivery, which make “ahhh jij bent romig” memorable in short edits, reposts and chat shares. It is still used because the phrase is instantly odd even to viewers who do not speak Dutch, so it works as a goofy reaction line, similar to other exaggerated reaction clips and goofy ahh sounds.
