The phrase comes from a Dutch-language Merci chocolate commercial broadcast in the 1990s, when Merci was widely marketed in the Netherlands as a small gift to say thank you. The line, dat jij er bent, fits that idea directly, thanking the person receiving the chocolates simply for being there. Decades later, the moment survives online as a very short soundboard clip, shared by people who remember the advert and by creators looking for a sincere Dutch thank-you. Its brevity and nostalgic television feel help explain why it still appears in edits today.
