Kankergrappig is Dutch internet slang, combining a strong Dutch intensifier with the word for funny, and it is used online to describe something extremely funny rather than as a formal expression. The short clip circulates as a reaction sound in Dutch meme culture, where a single blunt word can carry the whole joke without explanation. Because it is only about a second long, it fits easily into short videos, edits and message replies, and its appeal comes from that directness: it is short, recognisable to Dutch-speaking viewers, and instantly signals that something was far funnier than expected.
