There is no widely documented origin for Chiggers as a named soundboard clip, so it is best understood as a short online sound effect rather than a quote from a film, show or game. Its appeal comes from the word itself, which already suggests tiny, irritating bites, and creators have picked it up for reaction edits, pranks and short-form videos where a brief burst of discomfort makes a joke land faster. Because it is short and instantly recognisable as an itch or annoyance gag, it keeps circulating in meme edits rather than fading after one trend.
