They Know What Is What But They Don't Know What Is What They Just Strut, continued What The Fuck, is a lyrical phrase originally from the 2000 Roland Clark song "I Get Deep." It was sampled in Fatboy Slim's 2001 song "Star 69" and again in Katy Perry's 2017 song "Swish Swish." The phrase started to see use in memes around 2019. In 2021, an Original Sound consisting of the audio clip from Katy Perry's song became popularized on TikTok in lip-dub videos.
In 2000, house music producer Roland Clark released the song "I Get Deep," containing the lyrics, "They know what is what but they don't know what is what they just strut, what the fuck" (shown below).
On April 23rd, 2001, Fatboy Slim released the song "Star 69," which includes a modified sample of the Roland Clark lyrics over a beat (shown below, left).
