Short Tim Curry clips circulate online because his voice is instantly recognisable, even in a single word, and this parasites clip fits that pattern perfectly. It is shared on soundboards as a compact reaction sound, rather than as a longer scene, which makes it easy to drop into short videos, streams and edits. Its appeal lies in the contrast between the polished, theatrical delivery and the unpleasant subject, turning a simple word into a joke about invasion, infection or unwanted guests. That versatility keeps it useful long after its original context has faded from view.
