No widely documented source has been attached to this clip, so it is best understood as a short piece of user-shared soundboard audio rather than a line from a known film, show, or song. Its appeal online comes from its specificity: a drink order that sounds both precise and oddly incomplete, which makes it easy to repurpose as a reaction or a scene-setting detail. Short spoken clips like this tend to circulate through edits and memes because they are instantly recognisable in context, even without a famous origin, and this one survives for the same reason.
