The line comes from Blackadder, the British historical sitcom famous for Edmund Blackadder's elaborate, withering insults. Across its different series the character built a reputation for creative put-downs that were far funnier than simple swearing, and short clips of those lines later spread online as reaction sounds and soundboard favourites. This skunk comparison fits that tradition perfectly, combining a revolting image with perfectly serious delivery. It remains popular because it can insult someone playfully without sounding genuinely aggressive in modern edits and memes.
