The clip comes from King of the Hill, the animated sitcom created by Mike Judge and Greg Daniels that ran from 1997 to 2010, and was later remixed in YouTube Poop videos. Those early YouTube edits chopped dialogue from Hank Hill episodes into absurd new phrases, helping short Hank reactions circulate as memes. This particular two-second line survived because Hank's straight-laced persona clashes with the insult, making it reusable far beyond the original cartoon context.
