There is no single widely documented source for this short clip, so it is best understood as a soundboard reaction sound rather than a line from a known film or show. Short, easily looped phrases like this travel well on short-form video, where creators reuse them as shorthand for affection, admiration or playful swooning. Its French wording also gives it a slightly romantic, stylised feel that stands out from English reaction sounds, which helps it keep circulating in love-themed edits, couple content and lighthearted crush memes.
