This clip is shared online as a short, standalone animal sound effect rather than as a line from a known film or show, and its appeal comes from that simple mismatch of scale and behaviour. Short-form creators reuse it because it is instantly readable: a huge creature doing an ordinary thing needs no explanation, and the gulping sound does the comedy work on its own. That makes it a handy insert for dinosaur edits, thirst jokes and reaction videos, where a few seconds of wet, exaggerated drinking can turn a normal clip into something memorable without needing dialogue or context.
